Abstract

In this paper, we propose a comparison between experimental and simulated results of the transmission change of fused tapered fiber couplers exposed to uniform UV irradiation. Numerical simulations use the supermode propagation theory and reveals the decrease of the supermode propagation constant difference. This decrease induces a spectral shift of the coupler response to higher wavelengths and is found to be more significant for taper ratios corresponding to core to cladding mode transition. The model shows a very good agreement with experimental results observed for low power expositions.
