摘要	An optical device includes an optical waveguide through which light propagates and a micro-resonator structure including an optical sensor. The micro-resonator is configured to resonate at a wavelength of light that may be transmitted through the optical waveguide. When light at that wavelength is transmitted through the optical waveguide, it resonates in the resonator and is detected by the optical sensor to produce an electrical signal. The optical resonator may be a micro-cylinder, disc or ring resonator and may be coupled to the waveguide via evanescent coupling or leaky-mode coupling. Multiple resonators may be implemented proximate to the waveguide to allow multiple wavelengths to be detected. When the waveguide is coupled to a tunable laser, signals provided by the optical sensor may be used to tune the wavelength of the laser.
其他摘要	光学装置包括光传播通过其的光波导和包括光学传感器的微谐振器结构。微谐振器被配置为在可以通过光波导传输的光的波长下谐振。当该波长的光透过光波导时，它在谐振器中谐振并由光学传感器检测以产生电信号。光学谐振器可以是微圆柱形，盘形或环形谐振器，并且可以通过渐逝耦合或漏模耦合耦合到波导。可以在波导附近实现多个谐振器，以允许检测多个波长。当波导耦合到可调谐激光器时，光学传感器提供的信号可用于调谐激光器的波长。
