Real time implementation of packet-by-packet polarization demultiplexing in a 28 Gb/s burst mode coherent receiver

We experimentally show a real-time coherent receiver operated in burst mode. Enabled by special headers, 28-Gb/s PDM-QPSK packets with random states of polarizations are successfully demodulated, and the sensitivity to optical noise is reported.
