ABSTRACT:
An optical pulse generator includes a light emitting element that emits an optical pulse, and a driver. The driver is configured to apply a pulse driving current to the light emitting element to allow the light emitting element to emit an optical pulse. The driver is also configured to apply a preliminary driving current to the light emitting element prior to starting the application of the pulse driving current. The preliminary driving current is lower than a minimum level that needs to cause a stimulated emission of light.
