FONCTIONNEMENT DE MODE RAFALE PAR UN ÉMETTEUR-RÉCEPTEUR OPTIQUE ET PROCÉDÉ DE COMMANDE D'ÉMETTEUR-RÉCEPTEUR OPTIQUE FONCTIONNANT EN MODE RAFALE

摘要

The present invention provides an optical transmitter including a semiconductor laser and a control method thereof for preventing crosstalk between channels in an NG-PON2 with a 100 GHz channel spacing by reducing a wavelength drift of the semiconductor laser. The wavelength drift occurs between a few nanoseconds and a few hundreds nanoseconds from the beginning of a burst when the semiconductor laser is operated in a burst-mode.
