Homodyne coherent receiver with phase locking to orthogonal-polarisation pilot carrier by optical injection phase lock loop

Phase locking to an orthogonal-polarisation pilot by an optical injection phase lock loop is demonstrated for the first time, enabling homodyne demodulation of 10 Gb/s BPSK with performance close to the LO-ASE limit (OSNR=6 dB/0.1 nm; BER=10 -3 ).
