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.

 Generation of Kerr combs centered at 4.5 μm in crystalline microresonators pumped with quantum-cascade lasers

Optics Letters Vol. 40, No. 15 (2015)


We report on the generation of mid-infrared Kerr frequency combs in high-finesse CaF2and MgF2 whispering-gallery- mode resonators pumped with continuous-wave room- temperature quantum cascade lasers. The combs were centered at 4.5 μm, the longest wavelength to date. A frequency comb wider than one half of an octave was demonstrated when approximately 20 mW of pump power was coupled to an MgF2 resonator characterized with quality factor exceeding 108.

 Company Publishes "Ultra Low Noise Miniature External Cavity Semiconductor Laser

Pasadena, California – July 9, 2015 – OEwaves, Inc. (“OEwaves” or “the Company”), an innovator of microwave photonic technologies and products, is pleased to announce the publication of "Ultra Low Noise Miniature External Cavity Semiconductor Laser” in the June issue of Nature Communications.  Based on the proprietary ultra-high quality factor (Q) Whispering Gallery Mode (WGM) micro-resonator technology, OEwaves reports on the realization of a heterogeneously integrated, chip-scale semiconductor laser featuring 30 Hz integral linewidth as well as sub-Hz instantaneous linewidth in the article. 

Lasers with high spectral purity are key elements that determine the ultimate achievable sensitivity in advanced optical systems. Various applications, such as LIDAR, high resolution spectroscopy and optical sensing, quantum information science, atomic clocks, and spectrally pure photonic microwave generation require ultra-narrow linewidth lasers to optimize their performance. Beyond this, high data rate optical communications, including coherent communications, require lasers with low frequency and amplitude noise.

 “This paper describes the unprecedented performance of a miniature semiconductor-based laser.  Such a laser will better support many existing applications, as well as enabling a variety of new applications not previously possible” said Lute Maleki, President and CEO of OEwaves.

OEwaves proprietary high-Q WGM crystalline micro-resonators are capable of phase/frequency noise/linewidth reduction for a wide range of laser wavelengths in the UV, visible, and near and mid-IR regions.

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.
