摘要： The present invention provides a method and a circuit for increasing a time delay in an optical signal in an integrated optoelectronic circuit without a proportionate increase in the circuit area. The method uses multiple layers of optical waveguide fabricated in a vertical hierarchy in combination with concentric circular paths. The different sections of the optical waveguide delay line 103, 107 on the multiple layers are connected by electro-optic couplers to pass the optical signal between the sections. In a preferred embodiment, the optical couplers 105, 108 are a poled Electro-Optic (EO) region of cladding 506 allowing the coupler to be electrically addressed. Alternatively, in another embodiment, the couplers 105, 108 may be fabricated with a polymer that is optically nonlinear 406. This type of coupler could be addressed, or activated, by an optical signal, or a component of the optical signal traveling through the coupler.
摘要翻译：本发明提供了一种用于在集成光电子电路中增加光信号中的时间延迟而不增加电路面积的方法和电路。该方法使用垂直层级制造的多层光波导与同心圆形路径组合。多层上的光波导延迟线103,107的不同部分通过电光耦合器连接，以在各部分之间通过光信号。在优选实施例中，光耦合器105,108是包层506的极化电光（EO）区域，允许耦合器被电寻址。或者，在另一个实施例中，耦合器105,108可以用光学非线性406的聚合物制造。这种类型的耦合器可以被光信号或者通过耦合器的光信号的分量来寻址或激活。
