ABSTRACT:
An emitter of optical signals for optical fibers includes an electroabsorption modulator downstream of a laser and a Mach-Zhender modulator downstream of the electroabsorption modulator and controlled by at least one clock to eliminate for each pulse of the resulting signal from the first modulator a portion of signal in a time range including the rising edge and in a time range including the falling edge.
