OEwaves Article Appears in NATURE COMMUNICATIONS
Company Publishes "Ultra Low Noise Miniature External Cavity Semiconductor Laser"
Pasadena, CA (PRUnderground) July 9th, 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.
OEwaves, Inc., founded in 2000, is headquartered in Pasadena, California, USA. The company develops and offers state-of-the-art technologies and products in support of radar, communications, fiber-optic sensors, and test and measurement systems for military and commercial markets. OEwaves maintains an Intellectual Property Portfolio of 80 cases, 26 of which were licensed via an exclusive agreement with the California Institute of Technology (Caltech), to establish a secure path in which to develop its initial core technologies, the whispering gallery-mode (WGM) resonator and the opto-electronic oscillator (OEO).
