We investigate wavelength tunable 56 Gbit/s DQPSK systems using comb generation in a quantum-dash mode-locked laser. Relative intensity noise and bit error rate is measured for each mode. Error-free operation is obtained over 9 WDM channels with 100 GHz spacing.

    ABSTRACT: Semiconductor lasers, also denoted as laser diodes, are a key element in an increasing number of optoelectronic systems. The performance of these systems strongly relies on the performance of their component laser diodes. As an example, Fig. 1.1 shows a simple optical fibre communication system in which the laser diode converts electrical signals into optical signals, which are transmitted by an optical fibre and finally received by a photodiode.
