Nanosecond Opto-electrical Switches

Rapid development in optical communications, signal processing and time delay beam steering for radar applications has produced considerable interest in fast and efficient electro-optic switches and modulators. In this phase I program initially a comprehensive survey of the state of the art technology in electrically controlled switches will be done and several design options which satisfies the technical objectives like good insertion loss, low drive voltage, high speed and low cross talk will be selected. RAMAR proposes a novel electro-optic switch based on two metalcodiffusion technology. This design provides good insertion loss, low drive voltage, high speed and requires simple electrode structures to achieve switching speed in GHz regime.
