提出了一种基于SOI光子线波导的紧凑型阵列波导光栅（AWG）波长转换器。偏振不敏感的操作是通过一个特殊的偏振分集的方法，在该方法中，我们使用2-D光栅光纤耦合器作为集成偏振分束器。为了减轻工艺变化的影响，我们通过相同的AWG以相反的方向传播两个偏振，其占用面积仅为600 x 350 μ m（2）。这导致片上插入损耗在-2.1dB和-6.9dB之间，串扰为-15dB，并且仅为0.66dB的偏振相关损耗。这是在SOI纳米光子波导中实现的功能性偏振分集电路的第一次演示，包括与单模光纤的接口。(c)2007年，美国光学学会。
We present a wavelength duplexer based on a compact arrayed waveguide grating (AWG) in silicon-on-insulator (SOI) photonic wire waveguides. Polarization insensitive operation is achieved through a special polarization diversity approach in which we use 2-D grating fiber couplers as integrated polarization splitters. To mitigate the effects of process variations, we propagated both polarizations in opposite directions through the same AWG with a mere 600 x 350 mu m(2) footprint. This resulted in an on-chip insertion loss between -2.1dB and -6.9dB, crosstalk of -15dB, and only 0.66dB polarization dependent loss. This is the first demonstration of a functional polarization-diversity circuit implemented in SOI nanophotonic waveguides, including interfaces to single-mode fiber.
