This NSF-funded project [0642603] is a five-year (60 months) CAREER (Faculty Early Career Development Program) unified research and education development program. The full title of this project is “CAREER: Chip-scale low-power nonlinear optics using coupled resonators and CROWs”. The focus of this project is a study of the waveguiding principles and applications of a novel type of integrated photonics waveguide, the Coupled Resonator Optical Waveguide (CROW), in nonlinear optics at the milliwatt-scale power level, which is relevant for optical communications and signal processing.
