Abstract :
A compact, low-complexity all-optical carrier-recovery-unit for carrier-unsuppressed QAM signals is demonstrated for the first time. The carrier regeneration by laser injection-locking and recovered-carrier stabilization by linewidth sharpening have enabled successful homodyne-detection of 12 GBd carrier-unsuppressed QAM4 and QAM16 signals.
