Microscopic nanomechanical dissipation in gallium arsenide resonators
Mehdi Hamoumi, Pierre Etienne Allain, William Hease +5
We report on a systematic study of nanomechanical dissipation in high-frequency (approximatively 300 MHz) gallium arsenide optomechanical disk resonators, in conditions where clamp…
Improved optomechanical disk resonator sitting on a pedestal mechanical shield
Dac Trung Nguyen, William Hease, Christopher Baker +6
We experimentally demonstrate the controlled enhancement of the mechanical quality factor Q of GaAs disk optomechanical resonators. Disks vibrating at 1.3 GHz with a mechanical shi…
Ultrahigh Q-Frequency product for optomechanical disk resonators with a mechanical shield
Dac Trung Nguyen, Christophe Baker, William Hease +6
We report on optomechanical GaAs disk resonators with ultrahigh quality factor - frequency product Qf. Disks standing on a simple pedestal exhibit GHz breathing modes attaining a Q…
