Abstract :
Ultra-high Q microdisk resonators are fabricated and demonstrated on silicon-on-insulator platform. The presence of oxide substrate and a thin Si pedestal layer dramatically reduce the thermal resistance, thereby, increasing input optical power threshold for thermal instability. Critical coupling for a <2~2times106 is experimentally observed.
