单片集成玻璃光波导器件

Monolithic Integrated Glass Waveguide Device

制备了三元件集成玻璃光波导器件──两个光波导短程透镜、一个光波导光栅。采用Ｋ＋／Ｎａ＋交换方法制备光波导。制备的器件用半导体激光测试，用ＣＣＤ和示波器接收观察光信号。实验观察到光波导光栅的Ｂｒａｇｇ（布拉格）衍射，衍射效率为３０％。

Monolithic integrated glass waveguide device consists of three parts,two spheroidal geodesic lenses and an etched out waveguide grating.The waveguide was formed by K+/Na+ exchanging method.The device was measured with a semiconductor laser,and the optical signal received by CCD was displayed on an oscilloscope.The Bragg diffraction with an efficiency of 30 percent was observed experimentally.
