BANDWIDTH ENHANCED SELF-INJECTION LOCKED DFB LASER WITH NARROW LINEWIDTH

摘要

A laser system and method for self-injection locking. The system includes a laser (10) having a laser output at a frequency w0. An optical port (14) provides a portion of the laser output at the port and a modulator (16), coupled to the port, is driven by a RF signal at a frequency wm generates two sidebands at w0 ± wm. A filter (18) passes one of the two sidebands; and an optical path (20) couples an output of the filter to the laser for injection locking.
