Abstract

A reconfigurable 1×2 wavelength selective switch, based on a Lyot filter and high birefringence nematic liquid crystals, is proposed. Simulations and experimental results of a reconfigurable switch are reported. Insertion losses from 3.4 dB and rejection ratios up to 15 dB are obtained in a two input channel system at 560 and 621 nm. Control voltages of 0 to 3VRMS are used.
