论文摘要
我们展示了采用高分子,波长尺度的波导的尼橙酸盐悬浮膜中的共线声音调节器。通过强烈限制光学和机械波,该调节器通过数量级的订单提高了一个构成声学和电力机械效率的人数。我们的设备演示标志着声学访问中的一项重要技术进步,该技术有望提供一类新型的紧凑型和低功率变速子,可调过滤器,非磁性隔离器和梁偏转器。
We demonstrate a collinear acousto-optic modulator in a suspended film of lithium niobate employing a high-confinement, wavelength-scale waveguide. By strongly confining the optical and mechanical waves, this modulator improves by orders of magnitude a figure-of-merit that accounts for both acousto-optic and electro-mechanical efficiency. Our device demonstration marks a significant technological advance in acousto-optics that promises a novel class of compact and low-power frequency shifters, tunable filters, non-magnetic isolators, and beam deflectors.
