  • Method and apparatus for compensating for wavelength drift
    Patent number: 10700788
    Abstract: A method and an apparatus for compensating for wavelength drift are disclosed. The method includes: generating, by a burst control circuit, a burst bias current; sending, by the burst control circuit, the burst bias current to a light emitting part and a trigger; converting, by the trigger, the received burst bias current into burst DA data; sending, by the trigger, the burst DA data to a synthesizer circuit; receiving, by the synthesizer circuit, the burst DA data sent by the trigger and the calibrated DA data sent by the MCU respectively; synthesizing, by the synthesizer circuit, the burst DA data and the calibrated DA data to obtain a synthesized signal; and sending, by the synthesizer circuit, the synthesized signal to a temperature control part.
