Abstract

We present a double time-multiplexed interferometer based on Faraday mirrors, which can be used for two quantum cryptography channels. Two channel operation with "star" configuration, 1km + 1km telecom optical fibers, was demonstrated. Experiments show a fringe visibility of 0.96 for both channels. Crosstalk attenuation more than 70dB was observed.
