Detailed comparisons are made of the results of two approaches to the problem of nonlinear refraction at frequencies just below the band edge in semiconductors. The physical origin o f the nonlinear dispersion is taken to be direct saturation of independent, T 2 -broadened band states in the first model discussed. In the second model the refraction associated with a dynamic Burstein-Moss shift of the absorption edge is considered. Both models predict an extremely large nonlinearity, X (3) ≈ 1 e. s. u., of importance in the field of dispersive optical bistability and consistent with experimental observations of bistability, two-beam differential gain and four-wave mixing.

Optical phase-conjugation (OPC) was observed in Acid blue 9 dye-doped gelatin via degenerate four-wave mixing (DFWM) using a low-power He-Ne laser at 633 nm. Phase-conjugate (PC) signal measurements were made by varying the angle of incidence between the forward-pump beam and the probe beam in the degenerate four-wave mixing geometry. Growth of phase-conjugate signal with respect to the recording time was also measured. Finally double-exposure phase-conjugate interferometry was demonstrated in these dye doped gelatin films.
