Abstract
A method () includes a gain current (I) to an anode of a gain-section diode (D) disposed on a shared substrate of a tunable laser (), delivering a modulation signal to an anode of an Electro-absorption section diode (D) disposed on the shared substrate of the tunable laser, and receiving a burst mode signal () indicative of a burst-on state or a burst-off state. When the burst mode signal is indicative of the burst-off state, the method includes sinking a sink current (I) away from the gain current at the anode of the gain-section diode. When the burst mode signal transitions to be indicative of the burst-on state from the burst-off state, the method includes ceasing the sinking of the sink current away from the gain current and delivering an overshoot current (I) to the anode of the gain-section diode.
