Abstract

A 5-channel polymer/silica hybrid arrayed waveguide grating (AWG), fabricated through a simple and low-cost microfabrication process is proposed, which covers the entire O-band (1260-1360 nm) of the optical communication wavelength system. According to the simulation results, the insertion loss is lower than 4.7 dB and the crosstalk within 3-dB bandwidth is lower than ~-28 dB. The actual fiber-fiber insertion loss is lower than 14.0 dB, and the crosstalk of the 5 channels is less than -13.0 dB. The demonstrated AWG is ideally suitable for optical communications, but also has potential in the multi-channel sensors.

摘要

提出了一种通过简单且低成本的微制造工艺制造的5通道聚合物/二氧化硅混合阵列波导光栅（AWG），其覆盖了光通信波长系统的整个O波段（1260 - 1360 nm）。根据仿真结果，插入损耗低于4.7 dB，3 dB带宽内的串扰低于约 -28 dB。实际光纤到光纤的插入损耗低于14.0 dB，5个通道的串扰小于 -13.0 dB。所展示的AWG不仅非常适合光通信，在多通道传感器方面也具有潜力。
