Abstract

Ultra-high-quality (Q>4times10⁶) microdisk resonators are demonstrated in a Si₃N₄ platform at 655 nm with straight and curved in-plane coupling waveguides on a Si substrate. Selective coupling to specific radial orders and polarizations is demonstrated with phase-matching. TM modes show higher sensitivity to environmental modifications for sensing.
