抄録

We describe an injection-locked 64 QAM homodyne coherent transmission, which is the highest QAM multiplicity realized with an injection locking technique. The frequency locking range of the local oscillator (LO) was as wide as 1 GHz. The phase noise was only 0.2 deg, which is 1/3 of that obtained with our previous OVCO-based OPLL (0.6 deg.). As a result, a 120 Gbit/s polarization-multiplexed 64 QAM signal was successfully transmitted over 150 km with a simple receiver configuration and low DSP complexity.
