| 摘 要： | INTRODUCTION Because of high transparency of glass to light and the very stable physical properties of glass, waveguides made of it are popular structures and building blocks in optoelectronic applications. Par- ticularly they are often used to fabricate passive components or devices with good compatibility with optical fibers in optical communication. By adopting the technology available in microelectronics, fabri- cation of glass waveguides can be a standard process with mass production,…

| Abstract: | Thermally poled germanium-doped channel waveguides are presented. Multilayer waveguides containing a silicon oxynitride layer were used as charge trapper in this investigation on the effect of the internal field inside the waveguide. Compared to waveguides without the trapping layer, experimental results showed that the induced linear electro-optic (EO) coefficient increases about 20% after poling, suggesting strongly that the internal field is relatively enhanced, and showed it is a promising means for improving nonlinearity by poling in waveguides. |
