Abstract
The invention discloses an optical output power and output wavelength control system for use with a sampled grating distributed Bragg reflector (SGDBR) laser. The optical output power and output wavelength control system for use with a sampled grating distributed Bragg reflector (SGDBR) laser comprises a controller for providing current inputs to the laser controlling the optical output power and output wavelength and an external reference receiving an optical output from the laser and providing a reference output to the control, wherein the controller compares the optical output power and output wavelength of the laser to the reference output and locks the optical output power and output wavelength of the laser to the external reference.
