Research of Polymer Planar Optical Waveguide Sensing Characteristics

ABSTRACT

In order to research the sensing characteristics of polymer optical waveguide. In this paper, the theoretical model of transmission of three-layer polymer planar optical waveguide was established based on coupled-mode theory. The working principle of optical waveguide biosensor was investigated. The article also researched the relationship between an optical guide’s physical parameters and surface sensitivity and improved on the sensitivity calculation method of composite optical guide sensing components. This paper then goes on to establish a sensitivity analysis method for disappeared wave type sensing components. Based on this, the article has developed sensitivity calculation software for high sensitivity optical guide sensing components and improved film refraction rate of the method for sensitivity calculation.
