Integrated Polarization Beam Splitter Module for Polarization-Encoded Free-Space BB84 QKD

We present an integrated polarization beam splitter module for free-space BB84 quantum key distribution. The module is based on silica PLC birefringent Mach-Zehnder interferometer chip, and replaces successfully the bulk-optic-based polarization splitting subsystem of BB84 quantum key distribution test-bed operating at 780 nm.
