Polarization-Encoded BB84 QKD Transmitter Sourced by a SiGe Light Emitter

We demonstrate a polarization-encoded BB84 transmitter sourced by a SiGe light source and show that such a potentially "all-silicon" QKD scheme can operate well below the QBER threshold at which secret keys can be established.
