Abstract

We present an analysis of the performance characteristics of in-line fiber-optic bandpass and band-stop wavelength filters. A planar waveguide model was used for numerical simulations of the device performance. It was recently reported that the band-stop and the bandpass characteristics of a filter device depend on the depth of polishing of a single-mode fiber. However, our numerical simulations show that both types of filter characteristic can be obtained with the same depth of polishing.
