  • Electro-absorption bias circuit for electro-absorption modulators
    Patent number: 10615877
    Abstract: An electro-absorption bias circuit may include a temperature sensor. The electro-absorption bias circuit may include a controller to provide a temperature-dependent control signal based on data received from the temperature sensor. The electro-absorption bias circuit may include a power supply to provide an output voltage based on the temperature-dependent control signal from the controller. The electro-absorption bias circuit may include an electro-absorption driving circuit to output a bias voltage applied to the output voltage provided by the power supply.
    Type: Grant
    Filed: May 23, 2018
    Date of Patent: April 7, 2020
    Assignee: Lumentum Operations LLC
    Inventors: Ricardo Saad, Linda Liu, Yu-Ting Hsueh, Goutham Kumar
