中文摘要：
我们在场有极化 insensitivity 的一个电镀物品眼的过滤器的设计基于一个长时期波导栅栏。过滤器展出调节超过 35 nm 并且在一个偏爱电压范围盖住整个 C 乐队(1530 ～ 1565 nm ) 从的范围的极端大的波长 ? 84 ～ 84 V。在完整的调节范围，为伪 TE 模式的传播系数是超过 97% ， 3 dB 带宽在 0.8 nm 下面。到悦耳的电压的波长敏感是大约 0.208 nm/V。这个电镀物品眼的过滤器能在动态 WDM 网络被使用快波长扫描 / 选择，通讯隧道重构，并且光切换。
英文摘要：
We present the design of an electro-optic filter with polarization insensitivity based on a long period waveguide grating. The filter exhibits an ultra-large wavelength tuning range of exceeding 35 nm and covering the whole C band （1530 to 1565 nm） in a bias voltage range from -84 to 84 V. In the whole tuning range, the transmission coefficients for quasi TE modes are over 97% and the 3 dB bandwidths are below 0.8 nm. The wavelength sensitivity to the tunable voltage is about 0.208 nm/V. This electro-optic filter can be used in dynamic WDM networks for fast wavelength scanning/selection, communication channel reconfiguration, and optical switching.
