METHOD AND SYSTEM FOR PROVIDING THERMAL CONTROL OF SUPERLUMINESCENT DIODES

摘要

A method of stabilizing output characteristics of an SLD device (102) with respect to ambient temperature disclosed. The SLD device (102) includes a cooling module (114) for cooling an SLD chip (105), and a sensor (104) for providing a set point signal corresponding to a set point temperature. The cooling module (114) and the sensor (104) together with control electronics (106), form a feedback loop for maintaining the set point temperature within a predetermined range. The method comprises determining a variation of the output characteristics as a function of ambient temperature, and determining a variation of the set point signal as a function of ambient temperature, wherein the variation of the set point signal corresponds to the variation o f the output characteristics. The method also includes modifying the feedback loop so as to offset the variation of the set point signal, and thereby stabilize the variation of the output characteristics as a function of ambie nt temperature.
