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 16):
A method of controlling a headroom voltage of a laser driver, the laser diode being driven by a laser driver, a headroom control circuit connected to receive the headroom voltage of the laser driver, a DC-DC converter connected to receive an output out the headroom control circuit and to output a voltage Vout to an input of the laser diode, the method comprising:\n generating a controlled voltage based on the headroom voltage with the headroom control circuit; and generating a voltage Vout based on the controlled voltage with the DC-DC converter, and applying the voltage Vout as an input to the laser diode, wherein the headroom control circuit modifies the voltage Vout to compensate for high frequency reflections in the laser driver to maintain an optimized headroom voltage for the laser driver.
