Nondegenerate optical Kerr effect in semiconductors
Abstract
We calculate the nondegenerate bound electronic nonlinear refractive index n(sub 2)(omega(sub 1);omega(sub 2)) (i.e., an index change at frequency omega(sub 1) due to the presence of a beam at frequency omega(sub 2)) in semiconductors. We calculate this nonlinearity and its dispersion using a KramersKronig transformation on the calculated nondegenerate nonlinear absorption spectrum due to twophoton absorption, electronic Raman and optical Stark effects. The calculated n(sub 2) values and their dispersion are compared to new experimental values for ZnSe and ZnS obtained using a 2color Zscan.
