    摘要: A controller for use with sampled grating distributed Bragg reflector (SGDBR) lasers is presented. An exemplary controller includes a table of settings representing a control surface, each setting corresponding to a separate operating point of the SGDBR laser, a first mirror current controller and a second mirror current controller. The first mirror controller and the second mirror current controller respectively control a first mirror current and a second mirror current about an estimated extremum point of the control surface to substantially maintain alignment between each of a first mirror and a second mirror, and an associated cavity mode. The first mirror current and the second mirror current can be locked at a substantially fixed distance from the extremum of the control surface.

    摘要: 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.
