We have constructed and characterized several optical microring resonators with scale sizes of the order of 10 microm. These devices are intended to serve as building blocks for engineerable linear and nonlinear photonic media. Light is guided vertically by an epitaxially grown structure and transversely by deeply etched air-clad sidewalls. We report on the spectral phase transfer characteristics of such resonators. We also report the observation of a pi-rad Kerr nonlinear phase shift accumulated in a single compact ring resonator evidenced by all-optical switching between output ports of a resonator-enhanced Mach-Zehnder interferometer.
我们构建并表征了几个尺寸在10微米量级的光学微环谐振器。这些器件旨在用作可设计的线性和非线性光子介质的构建模块。光通过外延生长结构进行垂直引导，并通过深度蚀刻的空气包覆侧壁进行横向引导。我们报告了此类谐振器的光谱相位转移特性。我们还报告了在一个紧凑的单环谐振器中观察到的π弧度克尔非线性相移，这由谐振器增强马赫曾德尔干涉仪输出端口之间的全光开关所证实。
