摘　　要：简述用于无源光网络(PON)的平面光波回路(PLC)光电集成器件的3个关键技术,包括表面贴光子技术,半导体激光器(LD)、光电二极管探测器(PD)、光纤与波导的无源对准技术,非气密高可靠塑料封装。理论上分析了光纤与波导的耦合情况,通过仿真拟合曲线推断出了光纤与波导的z向偏移3dB容差为70μm,角度偏移3dB容差在5°以内。对样品进行了测试,高温下灵敏度为(-30.7±0.3)dBm,常温下为(-31.3±0.2)dBm,低温下为(-31.2±0.2)dBm,常温下光功率为(2.0±0.5)dBm,眼图清晰无干扰,结果表明PLC光电集成器件具有良好的稳定性能。Three key technologies of planar lightwave circuit （PLC） opto-electronic integrated devices for passive optical network （PON） are introduced briefly, including surface mounted photonics, passive alignment of the laser diode （LD）, photo diode （PD）, fiber and waveguide, as well as non-hermetic and high reliable plastic packaging. The coupling of optical fiber and waveguide is analyzed in theory, thus through simulation fitting curves it infers that the 3 dB tolerance of z offset of the fiber and waveguide is 70 μm, and the 3 dB tolerance of angle offset is less than 5°. The results of sample test show that the sensitivity is （--30.7±0.3） dBm in high temperature, （--31.3±0.2） dBm in normal temperature, （- 31.2 ±0.2） dBm in low temperature. Optical power in normal temperature is （2.0 ± 0.5 ） dBm with clear eye diagram. The results show the PLC opto-electronic integrated device has good stable performance.
