ABSTRACT:
The present invention is directed to a method and system for providing a three-level current scheme to a semiconductor laser to control beam wavelength and laser temperature. A first current is received into a gain section of the semiconductor laser and at least one other current is received into a DBR and/or phase section of the semiconductor laser. This other current(s) is pulse-width modulated based upon a required temperature value. An output beam is generated by the semiconductor laser based upon the received first current and the received pulse-width modulated current(s).
