Abstract
A tunable channel transmitter system for a wavelength division multiplexed (WDM) passive optical network (PON) includes a WDM communication system having a plurality of WDM channel bandwidths, an injection-locked Fabry-Perot laser having a plurality of resonant modes, a seed light source to provide seed light to the injection-locked Fabry-Perot laser, and a temperature control element configured to shift the plurality of resonant modes of the injection-locked Fabry-Perot laser to ensure that only one resonant mode of the injection-locked Fabry-Perot laser is locked to the seed source and transmitting a substantial portion of the laser power through a desired channel of the WDM communications system.
