We report the application of bandgap resonant nonlinear refraction to optical amplifier and switch devices - based on a nonlinear Fabry-Perot interferometer constructed from an InSb crystal. One such device, called a "transphasor", amplifies small power changes in one laser beam to give larger changes in a second. The effects are interpreted by a microscopic mechanism which includes the effects of power broadening as a contribution to ?(3) to explain its large value of ~ 10-2 esu. © 1979.
