OEwaves Offers Core Micro-Cavity Technology

Company To Offer Proprietary Whispering Gallery Mode (WGM) Optical Cavity

 Pasadena, California – October 22, 2014 – OEwaves announces ultra-high quality factor (Q) Whispering Gallery Mode (WGM) optical cavity product.  For the first time since the development of the unique WGM micro-resonator technology already utilized in OEwaves ultra-low phase noise microwave oscillator and ultra-narrow linewidth laser product families, the resonator is being offered as a stand alone high-Q and high finesse optical cavity product for use in diverse applications requiring high performance lasers and optical filters.  The resonator is integrated with input-output optics to enable user friendly coupling procedure.

 Based on a variety of crystalline and amorphous materials, WGM micro-resonators  feature greater than 109 optical quality factor.  They can operate as Fabry Perot cavities suitable for laser stabilization and optical filtering applications.  With just a few milli-meter in diameter, the stand-alone WGM micro-resonator offers a free spectral range (FSR) of 10-90 GHz, resonance contrast greater than 50%, and a frequency stability of about 10-10 at one second.  The cavity is compatible with wavelengths in a wide range, from UV to IR.

 “We are pleased to offer this unique product to make possible miniature, high performance laser systems, and optical filters” said Lute Maleki, President and CEO of OEwaves. “These devices in turn allow realization of small, hand held instruments where high performance lasers and optical filters are required.”

 Available in a compact form factor, OEwaves’ unique WGM cavity is customizable with various optional performance and features including fiber-optimized coupler, custom loading, custom FSR (within 10-90 GHz range), transmission and/or reflection ports as well as thermal stabilization. The packaged WGM micro-resonator is optimized for applications in at least 100 nm-wide selectable wavelength region belonging to either ultra-violet, or visible, or near and mid-infrared spectral range.
