MEMS based optical phase modulator using directional coupler

Continuous growing demand of real time computing originate frequent need of much faster processors than those are already available. There is a prompt evolution of new optical communication related application and components to fulfill these requirements. The attempt of combining these two methods leads to the generation of optoelectronic devices. The new device is MEMS based nanoscale silicon on insulator photo activated modulator using directional coupler. The design, simulation & characterization of an optoelectronic device based on Si which is capable of speeding up the processing capabilities have been presented in this paper. In this control command is sent optically and the nature of data flow is electronic. Faster operation rates are expected with the device. This optical device can serve as a building block of optical data processing while breaking through the way to all optic processors based on Si chips.
