Bit error rate (BER) characteristics at 18 Gbit/s generating the 330 GHz carrier from: (a) an actively phase stabilized reference source18, (b) the dual hybrid InP/Polymer DBR with −8 dBm optical injection power from the OFCG, and (c) free-running dual hybrid InP/Polymer DBR lasers and using direct detection at receiver. The inset shows the eye diagram under conditions of (b).
