We demonstrate a compact, single-chip 40-channel, dense wavelength division multiplexing (DWDM) variable attenuator multi/demultiplexer (VMUX/DEMUX) by monolithic integration of an echelle grating and high-speed p-i-n VOA on the silicon-on-insulator (SOI) platform. The demonstrated device has a flat-top filter shape, on chip loss of 5.0 dB, low PDL of 0.3 dB after compensation of the polarization dependent frequency (PDF) shift, a fast attenuation response speed of 3 MHz, and an area of only 25 mm by 10 mm.
我们通过在绝缘体上硅（SOI）平台上对阶梯光栅和高速p-i-n可变光衰减器（VOA）进行单片集成，展示了一种紧凑的单芯片40通道密集波分复用（DWDM）可变衰减器复用/解复用器（VMUX/DEMUX）。所展示的器件具有平顶滤波器形状，片上损耗为5.0 dB，在补偿偏振相关频率（PDF）偏移后偏振相关损耗（PDL）低至0.3 dB，衰减响应速度快达3 MHz，面积仅为25 mm×10 mm。
