在1.5 μm光波长，首次研制出质子交换铌酸锂光波导TE0模偏振器。器件由嵌在Ti扩散波导之间的一段质子交换波导构成，器件长度为2 mm。实验测得，偏振器的消光比和带尾纤插入损耗分别为42 dB和4.3 dB。

At 1.5 μm wavelength, TE0 optical waveguide polarizers have been fabricated in LiNbO3 by proton exchange for the first time. The polarizer consists of a short proton exchanged waveguide segment between the segments of a discontinuous Ti-indiffused waveguide. The length of the polarizers is 2 mm. The measured polarization-extinction ratio and fibre-coupled insert loss of the polarizers are 42 dB and 4.3 dB, respectively.
