The paper introduces a silica-on-silicon monolithic integrated cyclic arrayed waveguide grating (AWG) with Mach-Zehnder interference (MZI) filters and arrayed vertical reflecting mirrors in silicon to realize effective and stable optical transmission between waveguides and photodiodes. The cyclic AWG acts as both multiplexer over the L-band for upstream traffic and demultiplexer over the C-band for downstream traffic. The integrated chip, including AWG, MZI filters, and arrayed reflecting mirrors, has been made successfully with a 6.0 dB insertion loss, which is less than the discrete devices. At the same time, the arrayed reflecting mirrors are more stable than separate reflectors.
本文介绍了一种硅基单片集成环形阵列波导光栅(AWG),其带有马赫-曾德尔干涉(MZI)滤波器和硅基阵列垂直反射镜,以实现波导与光电二极管之间有效且稳定的光传输。环形AWG在上游业务的L波段用作复用器,在下游业务的C波段用作解复用器。包括AWG、MZI滤波器和阵列反射镜的集成芯片已成功制造出来,插入损耗为6.0 dB,低于分立器件。同时,阵列反射镜比分立反射器更稳定。
