Abstract

The Goos-Hänchen shift (GHS) can be measured typically by fixing the wavelength of incident light and changing the angle of incidence to analyze the optical modulation characteristics of the film material or its relevant parameters. In this paper, the membrane structure of one-dimensional photonic crystals (1DPC) was analyzed by varying the wavelength of incident light combined with GHS measurements. The theoretical analysis and experimental results show that the spectrum-GHS analysis method can show the band gap of 1DPC well and enhance the GHS, so as to improve the sensitivity of the prism-type sensors with 1DPC film sensitive layer. The abstract summarizes key findings in the paper.
