Research of Polymer Planar Optical Waveguide Sensing Characteristics

Abstract

In this paper, the theoretical model of transmission characteristic of microring resonators was established based on coupled-mode theory to get microring resonator resonance wavelength, free spectral range and other performance indicators. Working principle of optical waveguide microring biosensor was investigated. The article also researched the relationship between optical guide physical parameter and surface sensitivity and improved composite optical guide sensing components sensitivity calculation method and then established disappeared wave type sensing components sensitivity analysis method. Based on this, the article has developed sensitivity calculation software for high sensitivity optical guide sensing components and improved film refraction rate of calculation method for sensitivity calculation.
