The asymmetric five-layer optical waveguide model is used to analyze the characteristics of fiber Bragg reflection filters, and the structural parameters of narrow-band and broadband high-reflection filters are discussed. The article reports on the experimental study of fiber Bragg reflection filter, including the production process and test methods. A typical fiber Bragg reflection filter has a reflectivity of 80% and a bandwidth of 1.5 nm in the 1.5 μm band.
