Paper Abstract

We present a promising integrated single photon receiver module based on an electro-optic waveguide polarization decoder and a TM pass polarizer. Linear and circular detection bases can be selected with a low control voltage of ~1.5V. A TM pass waveguide polarizer was fabricated with an extinction ratio of greater than 40dB. Low quantum key error rate can be expected due to the reduced optical background scattering noise using the index-matched integration approach. The proposed receiver module is promising for free space quantum key distribution.
