摘要
通过固定两写入光束为90°,以垂直于介质入射面方向为转轴转动晶体的方法记录多重光栅,多重体全息光栅由于其严格的波长角度选择性可应用于多波长解复用.对相同方向入射的多波长光的有效分离,此方法制作波分复用器简单易行,可复用通道数目多等优点.
The holographic gratings are superimposed in the crystal with rotation multiplexing in the geometry .volume holographic gratings used for WDM attract widely attention due to their excellent angle and wavelength seleetiities. Muhwavelength illuminating the volume gratings in the same direction have been separated by the filter successfully. This method have many exeellenees to doing Wavelength division multiplexing simpleness.For example easy doing,high diffractive efficiency, many channels multiplexer and so on.
