Automatic power control circuit for a laser driver |
摘要 |
An automatic power control circuit for a laser driver which is responsive to a data signal for driving a laser diode includes a low pass filter connected to receive the data signal and generate an output signal dependent on the DC content of the data signal. A circuit responsive to both an externally provided average power control signal and the output signal of the low pass filter controls supply of operating current to the laser diode.
