摘要

本文说明了单模光纤与钛扩散铌酸锂(Ti:LiNbO

)条波导的耦合与波导的制作参数有关

我们制作了条宽W=6μm

长2.3cm(采用S型弯曲)的钛膜厚度为600A、750A、950A、1100A

扩散温度为1025℃

恒温9小时的Ti:LiNbO

条波导

并测得光纤-波导(2.3cm)-光纤插入损耗在950A(Ti)(W=6μm、T=1025℃

t=9h时为最小。

Abstract

This paper describes the influence of fabrication parameters on fiber-Ti:LiNbO

waveguide. We fabricated Tidiffusion waveguide with 6μm wide strip(associated with an S-shaped transition)

and 600A

750A

950A

1100A thicknesses at 1025℃ for 9 hour constant temperature. We have measured fiber-waveguide (2.3cm) -fiber insertion loss

showing that at λ=1.33μm and 950 thick with 6μm wide strip of Ti at 1025℃ for 9 hour constant temperature the loss is minimum.
