摘要：

A coupling wave optical waveguide sensor was proposed, and realized by combining the ion-exchange and the sol-gel methods. The new optical waveguide (OWG) sensor is based on a stacked slab optical waveguide codirectional coupler, and proved to be advantageous over conventional OWG sensors. A gas sensor fabricated as an example easily detected 5 ppm H2S.
