Abstract
A driving method of a laser diode includes setting a bias current, a modulation current, a first target corresponding to a predetermined average power, and a second target corresponding to a predetermined average modulation power; executing a first adjusting current step group; generating a temporary modulation current according to the modulation current; executing a second adjusting current step group; and executing the first adjusting current step group again.
