  • Temperature-locked loop for optical elements having a temperature-dependent response
    Patent number: 11005572
    Abstract: Examples described herein generally relate to a temperature-locked loop for optical elements. In an example, a device includes a controller and a digital-to-analog converter (DAC). The controller includes a DC-controllable transimpedance stage (DCTS), a slicer circuit, and a processor. The DCTS is configured to be coupled to a photodiode. An input node of the slicer circuit is coupled to an output node of the DCTS. The processor has an input node coupled to an output node of the slicer circuit. The DAC has an input node coupled to an output node of the processor and is configured to be coupled to a heater. The processor is configured to control (i) the DCTS to reduce a DC component of a signal on the output node of the DCTS and (ii) an output voltage on the output node of the DAC, both based on a signal output by the slicer circuit.
