OEwaves to Develop Compact Frequency Agile Opto-Electronic Oscillator for DARPA

OEwaves will develop and demonstrate a high performance, tunable opto-electronic oscillator (OEO) based on Whispering Gallery Mode (WGM) technology

Pasadena, CA - October 8, 2009 --[ASDWire]-- Drawing from knowledge gained in previous DARPA sponsored programs (aPROPOS and ChaSER), OEwaves, Inc. will demonstrate the feasibility of a compact, wideband tunable, ultra-high performance microwave oscillator suitable for radar and communication systems, to support small platforms such as Unmanned Vehicle Systems (UAS). The approach combines the use of a fiber based OEO for achieving high spectral purity with a unique modulator based on the optical WGM resonator. The anticipated ultra-low phase noise performance is expected to rival current single frequency compact OEO technology while providing the added advantage of wide band agility over 40 GHz.

A major feature of such architecture is the inherently low acceleration sensitivity, a parameter of significance for all mobile platforms. The outcome of this task can directly lead to a future development of high performance, miniature oscillators with exceptionally low acceleration sensitivity to enable availability of advanced radar and C4ISR capabilities for small UAV's and other small platforms.

"This program will lead to demonstration of a capability that currently does not exist, and will have a significant impact in enabling future radar and communications architectures." said Lute Maleki, President and CEO of OEwaves.

OEwaves' unique microwave photonic technology simplifies the architecture of conventional microwave techniques by addressing the critical need to substantially reduce size and power requirements. This is accomplished through the patented technology of ultra-high quality factor crystalline whispering gallery mode optical resonators. The small footprint of the product being developed serves to optimize the effectiveness of small platforms and their missions.
