Abstract

Density matrix theory is presented to explain recent experimental observations of intense optically induced magnetism due to a “mixed” type of nonlinearity proportional to the product of the electric- and magnetic-field strengths of light. Two previously unknown quadratic optical effects are predicted—namely, transverse optical magnetization and magnetic charge separation—and quantitative agreement is obtained with experimental results regarding the former of these. The mechanistic origin of a third quadratic nonlinearity, namely, magneto-electric second-harmonic generation, which is familiar on a phenomenological basis in classical nonlinear optics, is also examined. Transverse optical magnetism is shown to enable large permeability changes at optical frequencies accompanied by magnetic dispersion near resonances. This phenomenon provides for all-optical generation of magnetic moments, large transverse magnetic fields, static electric dipoles, and terahertz radiation in (unbiased) transparent homogeneous dielectrics or semiconductors. Intriguing possibilities for applications are considered, including magneto-electric refractive index modification, optical electric power generation, and spin control.

  19. Other applications of optical magnetism do not require operation near electronic resonances. The experiments of indicate that by programming the intensity of irradiation, large spatial variations of magnetic susceptibility could be induced over wide spectral ranges of transparency, limited only by the bandwidth of available light sources. Hence transformation optics applications with low losses may be feasible at optical frequencies in unstructured, transparent materials. For spintronics, mid-gap irradiation of semiconductor hosts is capable of generating large internal magnetic fields to lock the spin orientation of conduction electrons and lengthen their decoherence times. Although the induced magnetic field reverses with each optical half-cycle, spin precession proceeds without spin flips if the optical magnetic field greatly exceeds the dephasing fields and is prealigned with the quantization axis. In this way, spin coherence can be extended over long (illuminated) paths.

No radiation is generated at the fundamental frequency or its second harmonic via a quadratic E2 or B2 nonlinearity in effectively centro-symmetric media like liquids. Only susceptibility elements for nonlinearities driven by an EB field combination are allowed. The susceptibility tensor for second-harmonic generation (SHG) in a bulk centro-symmetric medium does have a nonzero element χzyx for the field combination ByEx, which emits radiation perpendicular to the pump beam. However, the radiation is at 2ω, unlike the MD radiation reported at the fundamental frequency ω in liquid samples in . In the present theory, the quantum mechanical symmetry requirement in a 2-level system is not inversion, but rather that R(y) and x transform identically. The ED and MD transition moments must simultaneously be nonzero between states 1 and 2, which dictates that the initial and final states have opposite parity. In multilevel systems this rule may be relaxed by virtual transitions to other states, rendering the process partly allowed in the presence of complete inversion symmetry. [CrossRef]
