| 摘 要： | 光通信系统要求可调谐光滤波器(TOF)隔离度高,偏振敏感性低,目前基于角度调谐滤光片技术的TOF很难满足这一要求.通过膜系仿真分析了此类TOF透射谱劣化的原因.针对不同偏振态的光束在倾斜入射时中心波长及带宽分离现象,提出一种对称反转光路对TOF透射谱进行优化,可在整个透射范围内(C波段)将TOF的隔离度提高到30dB以...

| Abstract: | Optical communication system requires the high isolation and low polarization sensitivity of Tunable Optical Filter (TOF). At present, the most of TOF based on thin film are hard to meet this requirement. The reason of TOF transmission spectrum degradation is analyzed by simulation. Referring to the center wavelength and bandwidth separation when different polarization beam in tilted incidence, an optimization design is proposed based on symmetric optical path. It improves the isolation of TOF to more than ... |
