论文摘要
提供光束偏转和光学频率转移的电驱动的声学设备具有广泛的应用，从脉冲合成到异差检测。市售的声学调制器基于散装材料和射频功率的消耗瓦特。在这里，我们演示了薄膜锂锂锂锂的集成的3-GHz声音频率变速杆，其载体抑制超过30 dB。此外，我们通过在0.6-THz光学带宽上换取了一个以上的Gigahertz间隔光频率梳，通过在主动频率换回路中循环光。我们集成的声学平台导致片上光学路由，隔离和微波信号处理的发展。
Electrically driven acousto-optic devices that provide beam deflection and optical frequency shifting have broad applications from pulse synthesis to heterodyne detection. Commercially available acousto-optic modulators are based on bulk materials and consume Watts of radio frequency power. Here, we demonstrate an integrated 3-GHz acousto-optic frequency shifter on thin-film lithium niobate, featuring a carrier suppression over 30 dB. Further, we demonstrate a gigahertz-spaced optical frequency comb featuring more than 200 lines over a 0.6-THz optical bandwidth by recirculating the light in an active frequency shifting loop. Our integrated acousto-optic platform leads to the development of on-chip optical routing, isolation, and microwave signal processing.
