Abstract

Wavelength-division-multiplexing (WDM) networks with wide channel grids and bandwidths are promising for low-cost, low-power optical interconnects. Wide-bandwidth, single-band (i.e., no free-spectral range) add-drop filters have been developed on silicon using anti-reflection contra-directional couplers with out-of-phase Bragg gratings. Using such filter components, we demonstrate a 4-channel, coarse-WDM demultiplexer with flat passbands of up to 13 nm and an ultra-compact size of 1.2 × 10(-3) mm(2).

摘要

具有宽信道网格和带宽的波分复用（WDM）网络对于低成本、低功耗的光互连很有前景。利用带有异相布拉格光栅的抗反射反向耦合器，在硅上开发出了宽带宽、单波段（即无自由光谱范围）的分插复用滤波器。使用此类滤波器组件，我们展示了一种4通道、粗波分复用解复用器，其平坦通带高达13纳米，超紧凑尺寸为1.2×10(-3)平方毫米。
