Abstract

We present detailed experimental and theoretical results for novel micro-optomechanical resonators, representing a significant improvement in the performance of such structures. These devices exhibit eigenfrequencies (f ) approaching 4 MHz, reflectivities exceeding 99.98% at 1064 nm, and mechanical quality factors (Q) of 0.8×10 (measured at 20 K and 2.5×10 millibar pressure); yielding a Q·f product of 3.1×10 Hz, while enabling a finesse of approximately 20,000 when used as an end mirror in an impedance-matched Fabry-Pérot optical cavity. These results represent a breakthrough in the development of optomechanical devices applicable to the emerging field of quantum optomechanics.
