Abstract
An optoelectronic device includes a laser diode, a driver and a reverse-bias circuit. The laser diode has a first terminal and a second terminal. The driver is coupled to drive current pulses through the laser diode between the first and second terminals. The reverse-bias circuit is configured to reverse-bias the laser diode during time intervals derived from the current pulses.
