Demonstration of Ultra-High-Q Silicon Microring Resonators for Nonlinear Integrated Photonics
A reflowing photoresist and oxidation smoothing process is used to fabricate ultra-high-Q silicon microring resonators based on multimode rib waveguides. Over a wide range of wavelengths near 1550 nm, the average Q-factor of a ring with 1.2-μm-wide waveguides reaches up to 1.17 × 10<sup>6</...
