Abstract :

Optical frequency comb, a Nobel Prize awarded research, is a new time and frequency standard with unprecedented precision. It has been the cornerstone for breakthroughs in ultrastable time keeping, astrophysical spectrography, attosecond sciences, highprecision navigation, high-capacity coherent communication, and high-speed nonlinear spectro-imaging. Recently, continuous-wave pumped microresonators emerge as promising alternatives to the current benchmark femtosecond laser platform. These photonic frequency combs are unique in their compact footprints and offer the potential for monolithic electronic and feedback integration, thereby expanding the already remarkable applications of optical frequency combs. In this talk, I will present my recent work on photonic frequency combs. I will first report the generation of stable 74-fs optical pulses from a Si3N4 microring resonator via numerical modeling and analytic theory, the connection between the microresonator parameters and the ultrashort pulse qualities. I will also report a low-phase-noise photonic frequency comb with 18 GHz comb spacing, compatible with high-speed silicon optoelectronics. I will describe the strategy to fully stabilize the photonic frequency comb and achieve a chip-scale optical frequency synthesizer with a relative uncertainty of 2.7├?┬?10-16. Finally, I will cover the future endeavour towards chip-scale precision metrology.
