1.3μm钛扩散铌酸锂波导薄膜偏振器

Ti:LiNbO_3 Waveguide Thin Film Polarizer for 1.3μm Wavelength

本文报道用于1.3μm 钛扩散铌酸锂(Ti∶LiNbO_3)波导 MgO/Al 薄膜偏振器,简述了工作原理,偏振器 TM 模消光比大于40dB 和可忽略 TE 模附加损耗。

The paper reports thin film MgO/Al polarizer on Ti:LINbO_3 wave- guide for λ=1.3μm.The priciple of operation is briefly described.The TM mode extinction ratio of the polarizer is better than 40dB with a negligible TE mode ex- cess loss.
