D. A. B. Miller and S. D. Smith, "Two Beam Optical Signal Amplification and Bistability in InSb," Optics Commun. 31, 101-104 (1979).

Reports on 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 chi /sup (3)/ to explain its large value of approximately 10/sup -2/ esu
