把光耦合进入薄膜光波导是集成光学器件的首要问题。本文报导了在离子交换光波导上沉积AZ-135光致抗蚀剂,用4880A°的氦镉激光器作光源,经滤波、扩束、分光在波导上以34°角相干曝光而制得全息光栅耦合器。我们已观察到在掩埋的光波导中沿着指定方向传输指定模式的光波。
Coupling light into thin film optical waveguides is a primary issue with integrated optics. This paper reports the deposition of AZ-135 photoresist on an ion-exchange optical waveguide using a helium-cadmium laser of 4880A ° as a light source. The holographic grating is obtained by coherent exposure of the waveguide at a coherent angle of 34 ° with filtering, expanding and splitting. Coupler. We have observed that in a buried optical waveguide a specified pattern of light waves is transmitted in a specified direction.
