Abstract

We study experimentally and numerically the transient behavior of a (2+1)D beam when it is totally reflected by nonlinear interface formed by SBN61:Ce photorefractive crystal. The dynamics give rise to observation of new beams. Due to modulation instability of the beam, the nonlinear interface stimulates the break of the beam into new beams that are reflected to different angles.

1. Introduction

The study of the interaction between radiation and mater at nonlinear interfaces opens the possibility of implementing several applications such as optical switching if a reflected beam is controlled varying the power of the input beam without changing the incident angle [1

]. Switching devices based on the interaction of spatial and temporal solitons have been suggested to exploit the effects of beam steering and mutual soliton trapping. The one dimensional case of total internal reflection has been studied experimentally and theoretically. Some physical characteristic effects observed in all cases are filamentation, optical bistability, surface waves, and Goos-Hänchen shift [8

]. The refraction of black and gray solitons was studied theoretically as well as the existence of a unique total nonrefraction angle for gray solitons Sánchez-Curto et al. [15

Recently, the physical phenomena of soliton reflection have been studied experimentally at the boundary of quadratic nonlinear media [16

]; in these works, the beam incident upon the interface of periodically poled LiNbO3, and linear beam transmission or soliton reflection was observed. Effects of remote boundaries on soliton dynamics in nonlinear media with a large range of nonlocality can lead to soliton steering and oscillation in predetermined trajectories [18

].

Other important physical phenomena in nonlinear interfaces are the arrays of spatial solitons. Scheuer et al. [19

19. J. Scheuer and M. Orenstein, “Oscillation modes of spatial soliton arrays in waveguides with nonlinear boundaries,” J. Opt. Soc. Am. B 19(4), 732–739 (2002). [CrossRef]

] investigated the dynamics of spatial soliton arrays, they found that the repulsive forces between the solitons are counteracted by the potential produced by nonlinear interfaces of the waveguide and stabilize array. Reflection and refraction of spatial solitons at the nonlinear interface formed by nematic liquid crystals were studied by Peccianti et al. [20

], one interesting result was the Goos-Hänchen shift effect.

The dynamics of propagation of (2 + 1)D beams is rather complicated. A question for (2 + 1)D beams was if they are stable; Saffman et al. [21

21. M. Saffman and A. A. Zozulya, “Circular solitons do not exist in photorefractive media,” Opt. Lett. 23(20), 1579–1581 (1998). [CrossRef] [PubMed]

] showed theoretically and numerically that the circular soliton do not exist in photorefractive media due to the direction of propagation. However, Shih and associates [22

22. M. F. Shih, M. Segev, and G. Salamo, “Circular waveguides induced by two-dimensional bright steady-state photorefractive spatial screening solitons,” Opt. Lett. 21(13), 931–934 (1996). [CrossRef] [PubMed]

] have observed experimentally solitons in photorefractive crystals with circular symmetry. Low order filamentation in anisotropic self-focusing media was reported by Zozulya et al. [23

23. A. A. Zozulya, D. Z. Anderson, A. V. Mamaev, and M. Saffman, “Solitary attractors and low-order filamentation in anisotropic self-defocusing media,” Phys. Rev. A 57(1), 522–534 (1998). [CrossRef]

] and they obtained large optical nonlinearities using low-power cw lasers in photorefractive materials. A detailed theory considering the propagation of (2+1)D beams in photorefractive media is presented by Saffman et al. [24

24. M. Saffman, G. McCarthy, and W. Krolikowski, “Two-dimensional modulational instability in photorefractive media,” J. Opt. B Quantum Semiclassical Opt. 6(5), S397–S403 (2004). [CrossRef]

]. They showed that single solitons are elliptical beams and include asymmetric filamentation into several beam lets in parallel direction of the external electric field. Other interesting results on (2+1)D propagation were reported by Carrasco et al. [25

25. S. Carrasco, S. Polyakov, H. Kim, L. Jankovic, G. I. Stegeman, J. P. Torres, L. Torner, M. Katz, and D. Eger, “Observation of multiple soliton generation mediated by amplification of asymmetries,” Phys. Rev. E Stat. Nonlin. Soft Matter Phys. 67(4), 046616 (2003). [CrossRef] [PubMed]

] in quadratic nonlinear media, with long distance of propagation (20 lengths diffraction) which consist of ring formation and splitting of the beam by a nonlinear interface formed by a photorefractive SBN61:Ce crystal and air.

In this paper, we report experimental results that show evidence of the formation of several beams stimulated by nonlinear interface in SBN61:Ce-air under application of an external electric field.

2. Mathematical model for the nonlinear interface

We assume that the light beam is launched within the nonlinear medium at an angle towards the lateral interface, as it is shown in Fig. 1
Fig. 1 Beam filamentation falling upon an interface between nonlinear and linear media.
.

If the beam approaches to the interface and is reflected, its peak intensity and width remains practically the same, proving that the V parameter is small enough. In consequence, the energy is approximately conserved during the reflection at the nonlinear interface [8

8. E. Alvarado-Méndez, R. Rojas-Laguna, J. G. Aviña-Cervantes, M. Torres-Cisneros, J. A. Andrade-Lucio, J. C. Pedraza-Ortega, E. A. Kuzin, J. J. Sánchez-Mondragón, and V. Vysloukh, “Total internal reflection of spatial solitons at interface formed by nonlinear saturable and linear medium,” Opt. Commun. 193(1-6), 267–276 (2001). [CrossRef]

]. Only this case is studied in this paper.

In Fig. 2(a)
Fig. 2 Numerical simulations of total internal reflection of the (2+1)D beam. a) input face; b) output face without voltage. The parameters are V=0.5, y0=5, x0=5, η=7.
the beam intensity in the input face is showed, the units are normalized, the interface is represented by a dotted line; Fig. 2(b) shows the reflected beam by the interface with V=0.5, x0=5, y0=5, μ=1 and η=7 parameters. The beam is self-focused perpendicular to propagation direction due to anisotropy of the photorefractive crystal (PRC) exhibited [27

27. A. A. Zozulya, D. Z. Anderson, A. V. Mamaev, and M. Saffman, “Self-focusing and soliton formation in media with anisotropic nonlocal material response,” Europhys. Lett. 36(6), 419–424 (1996). [CrossRef]

]. If the nonlinearity is increased (η=7), modulation instability effect produces oscillations in the beam when is launched to the interface (Fig. 3
Fig. 3 Numerical simulations of the broken up (2+1)D beam. The parameters areV=0.5; y0=5; x0=5; η=10.
); the beam is broken up in two new beams stimulated by nonlinear interface. For a best understanding of the interface we study the behavior of the beam in the interface for the stationary case.

The 2D modulational instability has been studied by Saffman et al. in photorefractive media [24

24. M. Saffman, G. McCarthy, and W. Krolikowski, “Two-dimensional modulational instability in photorefractive media,” J. Opt. B Quantum Semiclassical Opt. 6(5), S397–S403 (2004). [CrossRef]

]. However, the dynamics with nonlinear interface is different.

Two cases are presented. First, the effect on the beam when is launched to the nonlinear interface (Fig. 4(a)
Fig. 4 The beam propagation when: a) it is reflected by nonlinear interface, b) the beam is propagated in nonlinear medium without interface. In both cases the numerical values are x0=5, V=0.5, η=10.
); the graphic at the top shows propagation and reflection in the space; the graphic at the bottom is an orthogonal view. The high nonlinearity (η=10) and the interface brake the beam in two new beams. Second, when the beam is propagated without interface, oscillations in intensity are presented; nevertheless, the beam is not broken, Fig. 4(b).

For best clarity about the beam behavior when it interacts with the interface, we show the transversal profiles of the beam in x-y plane to different propagation distance (Z), only for one particular case (x0=5, η=10). We considered the stationary case; thus, there is dependence only on x-coordinate according to NLSE.

Fig. 6 The pictures (a), (c), and (e) correspond to the beam propagation within nonlinear interface. The pictures (b), (d) and (f) refer to the beam reflection with nonlinear interface, at different values of nonlinearity.
shows the comparison of the propagation of (2 + 1)D beam with and without interface; the total distance propagation is constant,Z=12, and with different nonlinearity values. Figures 6(a), 6(c), and 6(e) show the intensity profile of the beam without interface; Figs. 6(b), 6(d), and 6(f) show the reflected beam by the interface, with different values of nonlinearity (η=7,10,13, respectively). From Fig. 6, we observe symmetrical filamentation in the case without interface. However, if interface is considered, the asymmetrical filamentation of the beam takes place. These numerical results agree with the fission of N-soliton in planar waveguide [28

] and with theoretical research made by Ye et al. [29

].

3. Experimental setup

Two mirrors were used to control the angle of incident Gaussian beam (2+1)D at the input face of the PRC. We study the special condition of total internal reflection of (2+1)D beams, that was obtained when the angle between the incident and normal of the input face was 2.57°, very close to the nonlinear interface. The beam was reflected totally by the face (001) without external electric field applied. In the experimental results, the output intensity distribution obtained for different external applied voltages are shown in Figs. 8
Fig. 8 Dynamics of the beam for 600 V/cm each 10 s. (f) the self-focusing beam is observed at 50 s.
-10
Fig. 10 Dynamics of the beam for 1000 V/cm each 10 s. (f) the beam is broken up in four new beams at 50 s.
. In each case the effect of an external applied voltage was studied as function of time, taking image each 10 seconds; 50s after, the beams were stable; the Figs. 8(a), 9(a)
Fig. 9 Evolution of the beam for 800 V/cm each 10 s. (f) the beam is broken up in two new beams.
, and 10(a) show the beam at the output face without voltage. 600 V/cm were applied in PRC and the temporal evolution of the reflected beam is shown in Fig. 8. After 50 seconds the beam acquires an elliptic form, reaching the steady state (Fig. 8(f)).

The output distribution presents an intense central elliptic beam surrounded by a low intensity modulated elliptic ring. The behavior obtained by the central lobe was very similar to that, reported by Zozulya et al. [23

23. A. A. Zozulya, D. Z. Anderson, A. V. Mamaev, and M. Saffman, “Solitary attractors and low-order filamentation in anisotropic self-defocusing media,” Phys. Rev. A 57(1), 522–534 (1998). [CrossRef]

] in the experimental confirmation of its theory presented in [24

24. M. Saffman, G. McCarthy, and W. Krolikowski, “Two-dimensional modulational instability in photorefractive media,” J. Opt. B Quantum Semiclassical Opt. 6(5), S397–S403 (2004). [CrossRef]

]; an initial circular symmetric Gaussian beam evolved to an elliptical beam.

In the case of 1000 V/cm after 20 seconds (Fig. 10(c)) the output distribution is very similar to the obtained at 20 s with 800 V/cm (Fig. 9(c)) and at 50 s with 600 V/cm (Fig. 8(f)). However, 40 s later (Fig. 10(e)), the main lobe reduced its intensity and gave rise to low intensity circular spots; it was possible to identify three circular spots, the main, with higher intensity aligned perpendicular to the interface and some irregular spots above of it.

Finally, for a better comprehension, numerical and experimental results are compared and shown in Fig. 11
Fig. 11 Numerical and experimental comparison: a) first case, transversal profile of intensity of the beam for 600 V/cm (Fig. 8(f)); b) numerical transversal profile intensity for η = 7.81; c) second case, 800 v/cm (Fig. 9(f)); d) numerical profile intensity for η = 10.42; e) third case, 1000 V/cm (Fig. 10(f)); f) numerical profile intensity for η = 13.1.
. We analyze the steady state of the beams at 50 s, regarding Fig. 10(f) pictures (8), (9) and (10). We found numerically three important regions of the nonlinearity (η) and accumulate phase by distance of propagation (Z) as function of nonlinearity, where the experimental parameters were, initial width of the beam 200 μm, linear refractive index of 2.33, electro-optic coefficient, r = 224 pm/V, length of the crystal L = 1 cm, and λ = 632.8 nm. First region, for 3η8, the beam is only self-focused after of TIR and is stable for 50 s (see Fig. 11(a) to η=7.81); second region, for 8<η11.5, the beam is launched to the nonlinear interface and it is broken after the reflection in two beams (see Fig. 11(b)) for η=10.42); third region, for η>11.5 (see Fig. 11(c)) for η=13.1) the beam is broken in multiple beams stimulated by the nonlinear interface, and the accumulating phase by the nonlinearity which depends on the propagation length. Values of the experimental nonlinearity have a constant difference among them of 2.6, approximately.

3. Conclusion

In conclusion, we have presented numerical an experimental results of the dynamics of total internal reflection of (2+1)D beams in nonlinear interface formed by SBN61:Ce PRC and air. When external electric field is applied, multiple beams appear in the parallel direction of application of the external electric field. The dependence of the intensity of the beam with electric field opens new applications for optical switching devices. Both results: experimental and numerical are consistent with each other.
