Single mode photonic circuit architecture and a new optical splitter design based on parallel waveguide mode conversion
Abstract:
The new single mode circuit (SMC) architecture is invented for photonic integrated circuits (PIC). This architecture allows using multimode waveguides or structures to construct a single mode operated PIC. The multimode sections used in such SMC based PIC possess strong lateral confinement so that the PIC can have high circuit density and high optical performance at the same time. A parallel mode converter structure is also invented here. Based on this parallel mode converter, a low loss optical splitter can be constructed for high index contrast waveguide system.
Abstract(Chinese):

新的单模电路（SMC）架构是为光子集成电路（PIC）而发明的。 该架构允许使用多模波导或结构构造单模操作的PIC。 在这种基于SMC的PIC中使用的多模部分具有强的侧向约束，使得PIC可以同时具有高电路密度和高光学性能。 此处还发明了并行模式转换器结构。 基于这种并行模式转换器，可以为高折射率对比度波导系统构建低损耗光分路器。
