Optical whispering gallery mode resonators for high spectral purity signal generation


Dans le cadre des conférences "LAAS Research & Technology" Andrey MATSKO, Chief Technology Officer of OEwaves Inc. (Pasadena), interviendra sur le thème "Optical whispering gallery mode resonators for high spectral purity signal generation” le mercredi 11 juillet à 11h au LAAS-CNRS.

Crystalline whispering gallery mode resonators (WGMRs) are characterized with kHz optical bandwidths achievable at room temperature. Such a narrow bandwidth enables their applications for generation of high spectral purity signals in both optical and radio frequency (RF) spectral domains. For instance, WGMR-based self-injection-locked semiconductor lasers can be created in visible and IR, and have characteristics better than any other laser of similar size. As the result, miniature gyroscopes and clocks become feasible. WGMR-based X-Ka-band microwave photonic oscillators are characterized with spectral purity unachievable in both optical and electronic devices of similar form factor. Kerr frequency combs generated in WGMRs pumped with continuous wave light result in generation of femtosecond optical pulses on a chip. The frequency comb integrated with a miniature agile laser can be utilized for optical frequency synthesis. These and other applications will be discussed and analyzed in the presentation.
