摘要
利用纳米压印工艺及对接生长工艺制作了基于分布反馈（DFB）激光器阵列的适用于波分复用光无源网络（WDM-PON）光网络单元（ONU）的低成本光源芯片。器件使用单片集成多模干涉器进行合波输出。测试结果显示，器件平均阈值小于10 mA，边模抑制比大于40 dB，波长调谐范围大于10 nm，出光功率大于0.2 mW。
Abstract
Low cost optical network unit (ONU) light sources based on tunable distributed feedback (DFB) laser array using for wavelength division multiplexing-passive optical network (WDM-PON) are fabricated by nanoimprint lithography (NIL) and butt-joint regrowth (BJR). The multi-mode interference coupler (MMI) is used as output device for the monolithic integrated device. The tested results indicate that, the threshold current is less than 10 mA, side mode suppression ratio (SMSR) is higher than 40 dB, tunable range is wider than 10 nm and output power is larger than 0.2 mW.
