Paper Abstract

We propose and demonstrate a novel elliptical microdisk resonator which enables single-mode operation with high quality (Q) factor. Such elliptical microdisk resonators with pedestal, which consist of plenty of smoothly changing bends with modified curvature radii, can easily achieve single-mode operation due to selective losses introduced by mode transmission mismatches and small curvature radii portion inside the elliptical microdisks. We fabricated the devices on silicon-on-insulator (SOI) platform. Single-mode resonance with high quality factor (Q) of ~105 was experimentally realized. Besides, the proposed elliptical microdisk provides larger coupling strength compared to normal circular microdisk, and hence enables critical coupling with easy-to-fabricate gaps.
