This invention describes a multi-mode optical switching device comprising several regions interfacing with inorganic semiconductors. Each mode generates positrons and a photocurrent in several regions in response to control signals of different wavelengths of light. The photocurrent in each mode independently modulate the transmission of the high frequency control signals. Multiple hybrid optical devices can be transformed into optical interfaces by using light impulses in a manner similar to the electronic gates used in electronic systems. These devices can also perform as optical switches and optical interfaces between photoelectric elements. Arrays of hybrid optical devices create the opportunity for signal processing.
