Abstract

In this paper, we present a quantitative theoretical treatment of coherent optical wave mixing effects between the two orthogonally polarized states of a beam. The analysis is carried out in two birefringent nonlinear optical media: liquid crystals and photorefractive crystals. In these recently observed crossed-polarization mixing processes, amplitude and polarization couplings are mediated by the so-called non-Lagrangian type optical nonlinearity^[1,2] which could be induced in most nonlinear materials, in conjunction with a coherent pump beam of mixed polarization, c. f. Fig. 1.
