DISCRETE PULSE CONTROL FOR PHASE RANDOMIZATION APPLICATIONS

원문 (중국어)

Techniques for controlling light/radiation emitted from a laser light source are disclosed, wherein electric supply signals of a laser light source are modulated for generating a plurality of fixed predefined working supply signals configured to drive the laser light source during time intervals in which the light/radiation thereby emitted is encoded with data, mid variable idle supply signals for driving the laser light source between the data encoding time intervals. The modulating comprises at least one of generating the idle supply signals to include random time intervals and fixed idle supply signal level/intensity greater than a lasing threshold of said laser light source, and/or generating the idle supply signals to include idle supply signals having random levels/intensities or randomly alternated levels/intensitics greater than a lasing threshold of said laser light source, to thereby affect random phase changes between said data encoding time intervals without reducing the supply signal below said lasing threshold.
