Optically Actuated Transitions in Multimodal, Bistable Micromechanical Oscillators
Lior Michaeli, Ramon Gao, Michael D. Kelzenberg +3
We experimentally demonstrate a new class of optomechanical nonlinearities in weakly damped micromechanical resonators, arising from the interplay between the Duffing nonlinearity,…

Direct Radiation Pressure Measurements for Lightsail Membranes
Lior Michaeli, Ramon Gao, Michael D. Kelzenberg +4
Ultrathin lightsails propelled by laser radiation pressure to relativistic speeds are currently the most promising route for flyby-based exoplanet exploration. However, there has b…
