[IEEE 2018 IEEE Photonics Conference (IPC) - Reston, VA, USA (2018.9.30-2018.10.4)] 2018 IEEE Photonics Conference (IPC) - Cavity Optomechanical Photothermal Sensors

摘要： We experimentally demonstrate a cavity optomechanical sensor that is actuated with gradient optical forces. The sensor can detect incident radiation via absorption and resulting photothermally-induced frequency shifts of the nanomechanical oscillator. Analysis suggests that nanostrain sensitivity and fJ-level energy detection are possible.
