摘要	A polarization independent, frequency selective coupler for coupling an optical signal having at least one wavelength and an arbitrary polarization state, the polarization independent, frequency selective optical coupler comprising: a first waveguide; and at least one second waveguide, a first portion of the at least one second waveguide being in close proximity to the first waveguide thus forming at least one evanescent coupling region, the at least one evanescent coupling region exhibiting a first phase match condition coupling the TM mode of an optical signal propagating in the first waveguide to the at least one second waveguide and a second phase match condition coupling the TE mode of the optical signal propagating in the first waveguide to the at least one second waveguide, the first phase match condition being different than the second phase match condition.
其他摘要	一种偏振无关的频率选择耦合器，用于耦合具有至少一个波长和任意偏振态的光信号，该偏振无关的频率选择光耦合器包括：第一波导;至少一个第二波导，所述至少一个第二波导的第一部分紧邻第一波导，从而形成至少一个渐逝耦合区域，所述至少一个渐逝耦合区域表现出耦合TM的第一相位匹配条件在第一波导中传播到至少一个第二波导的光信号的模式和将在第一波导中传播的光信号的TE模式耦合到至少一个第二波导的第二相匹配条件，第一相匹配条件是不同于第二阶段匹配条件。
