Abstract
The negative effects of kinking in the L-I characteristics of laser diode operation with respect to feedback control for laser diode current control is suppressed by either (1) combining the output of a plurality of laser diodes together or (2) by imparting a current modulation superimposed on the direct driving current of the laser diode in conjunction with a limited feedback bandwidth, or a combination of both approaches (1) and (2).
