Quantum dash actively modelocked Fabry-Perot laser module demonstrated as part of wavelength tunable RZ transmitter

摘要

A quantum dash Fabry-Perot actively modelocked laser module is tested as part of a 42.7 Gbit/s transmitter with more than 10 nm wavelength tunability. Its low chirp level is also assessed through chromatic dispersion tolerance measurements. Introduction: Modelocked laser diodes (MLLDs) have a great potential for many applications in optical communications, such as optical time-division multiplexing [1] or optical clock recovery [2, 3]. Furthermore, multi-wavelength lasers have become attractive as they enable one to obtain a large number of wavelength-division-multiplexing (WDM) channels from a single source [4, 5].
