Abstract
PURPOSE:To generate the optical pulse in sub-nano second with a simple unit easily, by applying the pulse having the amplitude of kink phenomenon to the semiconductor laser, and picking up the light via the uni-mode light guide as narrow pulse. CONSTITUTION:It is not necessary that the width of the pulse current generated with the drive source 2 producing current pulse can be narrow so much, and the semiconductor laser 1 connected to the drive source 2 produces kink, and it is constituted with the uni-mode optical guide 3 delivering the output light. By changing the amplitude of the current pulse from this drive source 2, the width of output light pulse can be controlled, making unnecessary the current pulse narrow in the width and having high peak value. Thus, the kink phenomenon is positively utilized and the optical pulse in sub-nano sec can easily by generated with a very simple unit.
