Abstract

Gallium phosphide microdisk optical cavities with intrinsic quality factors <i>Q<sub>i</sub> </i> ~ 2.8 x 10<sup>5</sup> at 1.5 &mu;m are demonstrated. No two-photon absorption is observed. Saturation of internal optical loss, and optomechanical coupling to radial breathing modes with g<sub>0</sub> ~ 30 kHz is observed.
