In this Letter, we show that digital optical phase conjugation might be utilized to construct a new kind of wavelength-selective switches. When incorporated with a multimode interferometer, these switches have wide bandwidth, high tolerance for fabrication error, and low polarization dependency. They might help to build large-scale multiwavelength nonblocking switching systems, or even to fabricate an optical cross-connecting or routing system on a chip.
在这封信件中，我们展示了数字光相位共轭可用于构建一种新型的波长选择开关。当与多模干涉仪结合使用时，这些开关具有较宽的带宽、对制造误差的高容忍度和低偏振依赖性。它们可能有助于构建大规模的多波长无阻塞交换系统，甚至可以在芯片上制造光交叉连接或路由系统。
