Abstract
Provided for herein is a method for generating random numbers, the method includes driving, using a power source and a controller controlling the power source, a surface emitting laser in direct modulation mode, wherein the direct modulation mode is controlled by the controller so that the surface emitting laser is alternately driven below and above the lasing threshold so that laser pulses are emitted from the surface emitting laser, wherein, for driving the surface emitting laser above the lasing threshold, a current is chosen so that the surface emitting laser operates within a bistability zone of the surface emitting laser, and wherein the method comprises detecting, by a photodetector, the laser pulses emitted by the surface emitting laser and generating random numbers from the detected laser pulses.
