Bidirektionale Umsetzungsanordnung zwischen optischen und elektrischen Signalen für ein Übertragungssytem

摘要

The device has a vertically integrated component which consists of an optically-controlled oscillator (20) which is formed on a negative differential conductance base. The combination produces an optical to millimetric wave conversion to provide a down conversion function. An upper assymetrical Fabry-Perot cavity (30) produces a microwave to optical signal conversion to provide an up conversion function. The Fabry-Perot cavity can be implemented within semiconductor layers and the oscillator can be formed from Gunn diodes, IMPATT diodes or from a superlattice structure.
