Abstract :
We demonstrate for the first time a fully functional 2.5 Gb/s EA-modulated wavelength-selectable laser module meeting all long-haul transmission requirements for stability, chirp, power and linewidth over 20 channels on a 50 GHz grid. Based on a highly integrated InP chip comprising a DBR laser, semiconductor optical amplifier, power monitor, and EA-modulator, the module also contains optics to ensure simultaneous long-term wavelength and mode stability.
