Abstract:
A circuit and method provide a headroom voltage for a laser driver driving a laser diode such that the laser diode provides signals to an optical communications device. The circuit includes a headroom control circuit receiving the headroom voltage from the laser driver, the headroom control circuit generating a controlled voltage based on the headroom voltage, and a DC-DC converter receiving the controlled voltage from the headroom control circuit generating a voltage Vout based on the controlled voltage, and applying the voltage Vout as an input to the laser diode. The headroom control circuit and the DC-DC converter are connected in a feedback loop with the laser diode to continuously provide the voltage Vout to the laser diode, and the DC-DC converter modifies the voltage Vout to compensate for burn-in characteristics or temperature drift of the laser diode over time to maintain an optimized headroom voltage for the laser driver.

Claim (Index 8):
A circuit for providing a headroom voltage for a laser driver driving a laser diode, the laser diode configured to provide signals to an optical communications device, comprising:\n a feedback loop circuit connected between the output of the laser diode and an input of the laser driver, the feedback loop configured to generate a voltage Vout based on the headroom voltage and to apply the voltage Vout to the input of the laser diode, wherein the feedback loop circuit is configured to generate Vout to compensate for high frequency reflections in the laser driver to maintain an optimized headroom voltage for the laser driver.
