Monolithic 40-GHz Mode-Locked MQW DBR Lasers for High-Speed Optical Communication Systems

The state-of-the-art of the development and fabrication of advanced 1.55-mum/40-GHz pulse laser modules with a monolithic InP-based mode-locked distributed Bragg reflector (DBR) MQW laser chip inside is reported, with respect to the future applications in high-speed optical communications. We emphasize the latest improvements for hybrid mode-locked devices, which integrate a saturable absorber or an electroabsorption modulator. We further illustrate different technical approaches that enable meeting predetermined frequencies and wavelengths, and which are at the same time promising with respect to high fabrication yields
