SELF-INJECTION LOCKING LIGHT SOURCE, METHOD AND SYSTEM FOR LIGHT SOURCE SELF-INJECTION LOCKING

摘要

embodiment of the invention is a polarization splitter, and the first self-injection locking lasers connected to the polarization splitter and discloses a self-injection locking light source and a second self-injection locking lasers. The polarization splitter, the first performing polarization combination on the polarization provided by the self-injection locking laser and said second self-injection locking laser and, for the received reflected light to perform the polarization division, and the reflected light of the first self- injection locked laser and to provide each of the second self-injection locking lasers, and configuration; The first polarization direction of the magnetic self-injection locking laser and said second injection locked laser is consistent with each of the two polarization directions of the polarization splitters. Embodiments of the present invention further provides a method and system, and a wavelength division multiplexing passive optical network (WDM-PON) system for a light source self injection locking. ;
