An ultracompact reflective arrayed-waveguide grating (AWG) (de)multiplexer based on Si nanowires is demonstrated for the first time (to our knowledge). Each waveguide in the array has an individual photonic crystal (PhC) reflector at its end, making the AWG layout design very flexible. An eight-channel AWG (de)multiplexer with a channel spacing of 400 GHz is demonstrated experimentally. The total size of the fabricated AWG is as small as 134mumx115mum. The excess loss of the fabricated reflective AWG (de)multiplexer is about 3-4 dB, and the crosstalk is about -12dB.
首次展示了基于硅纳米线的超紧凑反射阵列波导光栅(AWG)(解)复用器(据我们所知)。阵列中的每个波导在其末端都有一个单独的光子晶体(PhC)反射器,这使得 AWG 布局设计非常灵活。实验演示了一个具有 400GHz 信道间隔的 8 通道 AWG(解)复用器。所制造的 AWG 的总尺寸小至 134μm×115μm。所制造的反射式 AWG(解)复用器的附加损耗约为 3-4dB,串扰约为-12dB。
