Inhalt:
We describe recent advances in a homodyne-detection system with injection locking and its application for higher-order QAM coherent transmission. Injection locking enables precise optical carrier-phase synchronisation with a simple receiver configuration. We demonstrate a 320 Gbit/s, 256QAM-160 km transmission.
