Abstract

We characterize the nonlinear propagation of picosecond pulses in chalcogenide As₂S₃ single-mode fiber using a pump-probe technique. The cross-phase modulation (XPM)-induced sideband broadening and stimulated Raman scattering (SRS)-induced sideband amplification are measured in order to map out the Raman gain spectrum of this glass across the C-band. We extract the Raman response function from the Raman gain spectrum and determine the power and polarization dependence of the SRS. In contrast to previous work using As₂Se₃ fiber, we find that the As₂S₃ fiber does not suffer from large two-photon absorption (TPA) in the wavelength range of the telecommunications band. We achieved a 20 dB peak Raman gain at a Stokes shift of 350 cm⁻¹ in a 205 mm length of As₂S₃ single-mode fiber. The Raman gain coefficient is estimated to be 4.3×10⁻¹² m/W and the threshold pump peak power is estimated to be 16.2 W for the 205 mm As₂S₃ fiber. We also demonstrate that we can infer the dispersion of the As₂S₃ fiber and justify the Raman response function by comparing simulation and experimental results.
