We demonstrate optomechanics in the sub-terahertz regime. An optical racetrack resonator, patterned from thin-film lithium niobate, is suspended to support mechanical structures oscillating at these extremely high frequencies, which are read out through cavity optomechanical coupling. Our hybrid platform paves the way for advancing mechanical systems in the quantum regime at elevated temperatures.

亚太赫兹光力学


我们展示了亚太赫兹范围内的光力学。由薄膜铌酸锂制成的光学跑道谐振器被悬挂起来，以支撑在这些极高频率下振荡的机械结构，这些频率通过腔光机械耦合读出。我们的混合平台为在高温下推进量子领域的机械系统铺平了道路。
