Abstract
The device comprises a first opto-optical gate for resynchronization and a second opto-optical gate for amplitude regeneration, the signal output by the first gate being applied to the control input of the second gate. The device also includes an opto-optical gate for regenerating contrast which receives a signal to be generated both on a source input and on a control input. The opto-optical gate is a three-input Mach-Zehnder interferometer, with each of the two branches thereof having a respective semiconductor optical amplifier.
