We report an experimental demonstration of 40 Gbps all‐optical 3R regeneration with all‐optical clock recovery based on InP semiconductor devices. We also obtain all optical non‐return‐to‐zero to return‐to‐zero (NRZ‐to‐RZ) format conversion using the recovered clock signal at 10 Gbps and 40 Gbps. It leads to a good performance using a Mach‐Zehnder interferometric wavelength converter and a self‐pulsating laser diode (LD). The self‐pulsating LD serves a recovered clock, which has an rms timing jitter as low as sub‐picosecond. In the case of 3R regeneration of RZ data, we achieve a 1.0 dB power penalty at 10 −9 BER after demultiplexing 40 Gbps to 10 Gbps with an eletro‐absorption modulator. The regenerated 3R data shows stable error‐free operation with no BER floor for all channels. The combination of these functional devices provides all‐optical 3R regeneration with NRZ‐to‐RZ conversion.
