Broadband Dynamic Injection-Locking Performance of Fabry-Perot LD and Its Application to Coherent Homodyne Receiver

We describe the broadband injection-locking performance of a Fabry-Perot LD (FP-LD) whose dynamic locking bandwidth can be greatly extended to 28.8 GHz with a low Q-value FP-LD. Application to 256 QAM demodulation is successfully demonstrated.
