PASSIVE COMPONENT FOR ALL-OPTICAL REGENERATION OF HIGH LEVELS BY SATURABLE ABSORPTIONS CAVITY

摘要

The invention relates to a passive saturable absorbent component for the all-optical regeneration of an optical signal like those used for digital data transmissions, as well as a method of regeneration and a device implementing said regeneration. The invention also relates to a method and a system for manufacturing such a component. The invention proposes an optical component for processing an optical signal functioning by reflection in a saturable absorption resonant cavity (C1) formed between a first mirror (M1) called rear and a second mirror (M2) located beside the incident signal, the reflectivity of the second mirror being greater than or equal to the reflectivity of the rear mirror. In a second embodiment, the component comprises a third mirror (M3) set in a second cavity and monolithically performs a regeneration of the high and low levels.
