PR12 Long Silicon Photonic Coupled-Microring Coupled-resonator Optical Waveguides: Design and Fabrication (Project Report 0642603-Y3)

Abstract

This NSF-funded project [0642603] is a five-year (60 months) CAREER (Faculty Early Career Development Program) unified research and education development program, with a focus on the physics and applications of nonlinear optics in the CROW (Coupled Resonator Optical Waveguide) device structure. In wavelength conversion, the optical output power at the new wavelength (i.e., the idler) depends quadratically on the propagation length (in the low power regime). It is important to realize long CROW structures which requires designing slow-light waveguides with low loss and low disorder. As studied here, the fabrication of low-loss slow-light waveguides can be challenging due to several factors, including material losses, fabrication imperfections, and scattering losses.
