Abstract
A planar integrated optical waveguide chemical vapor microsensor has been fabricated on a glass substrate using a cw argon ion laser source to photopolymerize an initially bifunctional oligomer precursor. This fabrication technique allowed for the use of a relatively high refractive index photopolymerized transparent material to serve as both the light-guiding structure as well as the chemical sensing coating element simultaneously. Preliminary tests employing this structure in a continuously flowing nitrogen vapor system indicated that the sensing material can be used to detect the presence of ammonia and toluene vapors.Keywords
