论文摘要
众所周知,耳语画廊模式(WGM)是球体材料表面附近的循环模式,已知具有声学和电磁波的高质量因素。在这里,我们报告了一个电力力学系统,其中沿介电球的赤道的声波和光波重叠的WGM彼此强烈彼此。仅在单个边带中仅提供三重谐波相匹配条件,可提供大量的布里渊散射,并观察到从输入射频频率信号刺激声学模式到输出光学信号的转换。
Whispering gallery modes (WGMs), circulating modes near the surface of a spheroidal material, have been known to exhibit high quality factors for both acoustic and electromagnetic waves. Here, we report an electro-optomechanical system, where the overlapping WGMs of acoustic and optical waves along the equator of a dielectric sphere strongly couple to each other. The triple-resonance phase-matching condition provides a large enhancement of the Brillouin scattering only in a single sideband, and conversion from the input radio-frequency signal exciting the acoustic mode to the output optical signal is observed.
