摘　　要：提出了一种适合于宽带光波导耦合器的抗偏振变动、抗温度变动的优化设计理论和方法。使用该理论和方法 ,在 14 90～ 16 10nm带域上 ,对氟化聚酰亚胺光波导做了 3dB耦合器的消偏振和温度依存设计。器件经三维波束传播法 (BPM)模拟运行验证 ,结果表明 ,12 0nm带宽上 ,在 - 10～ 4 0℃的环境下 ,两个正交偏振态均实现了(5 0± 0 .8)A method for designing optimized polarization-independent and temperature-insensitive optical waveguide couples using fluorinated polyimide is presented. Based on measured polarization, temperature and dispersion characteristics of fluorinated polyimide, a 3 dB waveguide coupler with 120 nm bandwidth with minimal polarization and temperature variance is designed and verified through simulation based on three-dimensional beam propagation. The coupling ratio of the theoretical device is (50±0.8)% for two orthogonal polarization modes in the waveband 1490 -1610 nm and the temperature range -10-40°C.
