Abstract
Abstract Wavelength Division Multiplexing (WDM) is a key enabling technology for increasing the transmission capacity of optical fiber communication systems. Recently, a new family of optoelectronic devices, including detectors, switches, and emitters, that is based on resonant cavity enhancement, has emerged. Wavelength selective optoelectronic switching is achieved by placing a photothyristor in an asymmetric Fabry-Perot cavity, which provides a highly selective response at a wavelength determined during device fabrication. These WDM optoelectronic devices haue promising applications in optical COmmunications and optical logic circuits. Results on a N-p-n-p optoelectronic switch with a ten wavelength channel capability are presented.
