Abstract

A burst-mode laser driver includes a driver circuit, a switching circuit, and an energy recycling or harvesting circuit. The driver circuit is adapted to be electrically coupled to a burst-mode laser, the driver circuit configured to control a bias current supplied to the burst-mode laser to change the laser between the burst-on and the burst-off state. The switching circuit is electrically coupled to the driver circuit and adapted to switch the bias current between the laser during a burst-on state and a dummy electrical path during a burst-off state. The energy recycling circuit electrically coupled to the switching circuit and is adapted to harvest at least a portion of energy from the bias current during the burst-off state.
