取样光栅的反射谱特性及其应用

Research of the optical devices based on reflective spectrum characteristics for the sampled grating

本文基于取样光栅的独特反射谱特性,对其作为光子器件如DBR激光器、波分复用/解复器和光插分复用器 的结构图作了探讨。通过比较得知,用取样光栅构成的新型光子学器件比用单纯的光纤光栅构成的光子学器 件在未来的密集型波分复用(DWDM)光纤通信系统中更有实用价值。

The paper based on the special reflective spectrum characteristics for the sampled gratings, we madea research on the schematics of the optical devices like DBR lasers .wavelength division multiplexer/demultiplexer and optical add/drop multiplexer. By comparison between the optical devices made by sampled gratings and simple fiber gratings, we think sampled gratings will have much more value in the DWDM optical communication systems.
