A 40G RZ-DQPSK transmitter monolithically integrated with a tunable DFB laser array and Mach-Zehnder modulators was developed for the first time. The optical waveform of 40Gb/s DQPSK was successfully demonstrated.
We demonstrated experimentally a wavelength converter with a wide input power dynamic range of 14 dB for the nonreturn to zero format at 43 Gbps with an extinction ratio exceeding 12 dB.
We demonstrate an error-free all-optical 2times10.7 Gb/s NRZ-OOK to 10.7 Gsymbol/s RZ-QPSK modulation format conversion using a newly developed integrated SOA three-arm-MZI wavelength converter module.
Monolithically integrated wavelength converter based on semiconductor optical amplifier with distributed feedback laser diode is fabricated. Gain recovery time of 7 ps is achieved for the semiconductor optical amplifier in experiment with simulated optimization.
