Abstract
A burst mode laser transmitter includes a burst mode laser diode and a controller having an input for receiving an RF data signal. The controller includes a triggering arrangement and a modulation arrangement. The triggering arrangement is configured to bias the laser diode to an on-state bias level when an RF data signal is present at the input to the controller and to an off-state bias level when no RF data signal is present at the input to the controller. The modulation arrangement is configured to modulate the on-state bias level at which the laser diode is biased with the RF data signal only when the RF data signal is present at the input of the controller.
