    Design a driver for DFB laser

    Hello
    I want to design a drive for a DFB laser transmitter.
    I want guidance for circuit design.
    And whether you have micro-code source code?

    Re: Design a driver for DFB laser

    the following is intended as gently as possible

    read the instructions and specifications of your DFB laser
    do some research on how to produce the voltages/currents/power you need
    do some research on the appropriate modulation methods

    sketch out a circuit that may do the job
    simulate the circuit

    in short, put in some effort on your project, then ask questions
    this forum is about answering questions, not providing turnkey solutions
    you have to pay for those, but not here.

    Re: Design a driver for DFB laser

    Thank you for your guidance.

    I want to know what processor I can use to control the wavelength of a laser?

    Re: Design a driver for DFB laser

    I moved the thread to Analog Circuit Design section because it's only marginally related to microcontrollers.

    The wavelength of a DFB laser can be varied in very narrow limits by modulating the current. A microcontroller may play a role but is no essential means.
