Two-section gain-coupled DFB lasers for high-speed optical communication systems

The two-section gain-coupled DFB laser can be designed to exhibit self pulsing. The self-pulsing dynamics have been exploited to demonstrate a variety of application in high-speed optical communication systems, including wavelength and polarization-independent all-optical clock recovery up to 100 Gb/s and conversion from the NRZ or RZ format to CSRZ format.
