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1490～1610 nm带域上,对氟化聚酰亚胺光波导做了3 dB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,120 nm带宽上,在-10～40 ℃的环境下,两个正交偏振态均实现了(50±0.8)%功率输出比的良好特性。
Abstract
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 ℃.
