摘要	An optical wave power control device and method enables signal control, such as modulation and switching, to be effected within an uninterrupted propagation element, e.g. an optical fiber or planar waveguide. The propagation element is configured such that a portion of its wave guided power encompasses the exterior surface of the element, intercepting the periphery of an adjacent high Q volumetric resonator. Power of a chosen resonant wavelength is coupled into the resonator, where it circulates with very low loss in accordance with the principles of a whispering gallery mode device, and returns energy to the propagation element. By introducing loss within the resonator, the propagated power can be varied between substantially full and substantially zero amplitudes. Loss factors can be maintained such that the resonator is overcoupled, i.e. parasitic losses are less than coupling losses, and a critical coupling condition exists in which a small swing in the control effect causes a disproportionate change in the optical output signal.
其他摘要	光波功率控制装置和方法使得能够在不间断的传播元件（例如调制器）内实现信号控制，例如调制和切换。光纤或平面波导。传播元件被配置为使得其波导功率的一部分包围元件的外表面，拦截相邻的高Q体积谐振器的外围。所选择的谐振波长的功率被耦合到谐振器中，其中它根据回音壁模式装置的原理以非常低的损耗循环，并且将能量返回到传播元件。通过在谐振器内引入损耗，传播的功率可以在基本上完全和基本上零幅度之间变化。可以保持损耗因子，使得谐振器过耦合，即寄生损耗小于耦合损耗，并且存在其中控制效应中的小摆动导致光输出信号不成比例变化的临界耦合条件。
