A Study of Nonlinear Reflection and Optical Switching in Indium Antimonide

Abstract

Bistability in the reflected light from an Indium antimonides surface has been observed without the use of a resonance cavity, and is explained by an increasing absorption positive feedback mechanism. Relying on this mechanism, we demonstrate a novel InSb optical switch which uses only the surface reflection and operates at room temperature using a pulsed carbon dioxide laser as the pump beam. The polarity of the switched out signal, the probe beam, was found to depend on the wavelength of the probe beam in the visible and near infrared range. This novel spectral dependence was used to demonstrate several optical logic elements.
