5-(2-硫甲基-4-甲基-5-嘧啶基)-2,4戊二炔-l-醇α-甲基丙烯酸酯(PDMA)/PMMA的全光通道波导

All Optical Channel Waveguide in PDMA/PMMA Composite

利用Ａｇ＋－Ｎａ＋离子交换法形成了Ａｇ＋离子基底，在此基础上镀上ＰＤＭＡ／ＰＭＭＡ膜并在Ｙ型波导分支上进行局部紫外聚合，从而制成了较理想的通道波导。测定了ＰＤＭＡ／ＰＭＭＡ的线性折射率及Ａｇ＋离子基底的折射率，实现了较理想的复合波导传输。

In this paper, the Ag + substrate was formed by Ag +-Na + exchange method. And by plating the membrane of PDMA/PMMA on the substrate and polymerizing partly PDMA on a branch of Y-type waveguide under UV irradiation, we prepared high quality channel waveguide. The linear index of the refraction of poly-PDMA and the substrate were measured, and the transmission of complex waveguide was realized.
