Injection-locking is based on the fact that the laser can be locked onto the frequency and the phase of an external injected optical signal. When a Fabry-Perot laser diode (FP LD) is locked onto a single-mode signal, its operation becomes single-mode. The injection-locked FP LD (IL-FP LD) has been proposed as a standard component for optical access network(More)
In this paper we present our recent works on optical injection of Fabry-Perot laser diode for application in access networks. The injection-locked Fabry-Perot laser diode is used as low-cost colorless transmitters for high-speed optical access exploiting wavelength-division-multiplexing technology. The modification of main characteristics of Fabry-Perot(More)
This research carries out coherence measurements of a 42.7 GHz quantum dash (QDash) semiconductor laser when passively, electrically, and optically mode-locked. Coherence of the spectral lines from the mode-locked laser is determined by examining the radio frequency beat-tone linewidth as the mode spacing is increased up to 1.1 THz. Electric-field(More)
