First demonstration of a polarization insensitive low time jitter and optical noise tolerant all-optical clock recovery at 40 GHz using a self-pulsating laser tandem

We experimentally demonstrate a polarization insensitive all-optical clock recovery, tolerant for an input optical signal to noise ratio as low as 15dB/0.1 nm, by cascading a bulk-based and a quantum-dots based self-pulsating lasers at 4OGbit/s.
