Abstract: 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.

Abstract: Techniques, methods and system, for synchronization of sparse data signals are disclosed, comprising mixing a serial stream of sparse data signals with a serial stream of synchronization signals, to thereby add redundancy to the serial stream of sparse data signals and enable clock regeneration from a serial stream of mixed signals produced by said mixing, emulating the serial stream of synchronization signals by applying the clock regeneration to the serial stream of mixed signals, and generating a stream of parallel synchronization signals having a frequency of the serial stream of synchronization signals, deserializing the serial stream of mixed signals into a stream of parallel mixed signals having a data rate lower than a data rate of the serial signal streams, and demixing the stream of parallel synchronization signals with the stream of parallel mixed signals and thereby removing the redundancy introduced by the mixing into the sparse data signals and generating a parallel stream of demixed signals sub
