Company Publishes "High spectral purity Kerr frequency comb radio frequency photonic oscillator

Pasadena, California – September 17, 2015 – OEwaves, Inc. (“OEwaves” or “the Company”), an innovator of microwave photonic technologies and products, is pleased to announce the publication of "High spectral purity Kerr frequency comb radio frequency photonic oscillator” in Nature Communications. The publication describes OEwaves 10 GHz miniature Kerr frequency comb photonic oscillator with orders of magnitude superior in phase noise (-170 dBc/Hz at 10 MHz offset) and stability (10-10 at 1-100 seconds integration time) performance than any existing RF photonic devices of comparable form factor and power consumption in the article.  The oscillator is based on the proprietary ultra-high quality factor (Q) crystalline Whispering Gallery Mode (WGM) micro-resonator technology.

The superior phase noise performance of the Kerr comb oscillator draws upon the intrinsic spectral purity of optical resonances. Unlike conventional oscillators, the device exhibits inherently high natural oscillation frequencies, without the need for electronic frequency multiplication, which also multiplies the phase noise and adds considerable expense, size, power requirements, and vibration sensitivity. This approach is applicable for generation of spectrally pure signals anywhere in the range of 10-100 GHz, in a miniature form factor.

Microwave and mm-wave oscillators with ultra-low phase noise, high stability, and small size, weight, and power (SWAP) are widely sought after by next generation wireless data backhaul microwave and mm-wave radios, satellite communications, and airborne radars, in addition to highly sophisticated defense communication and sensor systems.
