Abstract
The invention relates to a diode capable of alternately operating as a detector and emitter of light in the same frequency band. This diode comprises an active zone disposed between two localizing zones and respectively forming two hetero-junctions with these zones. The reverse biassing voltage is such that the active zone is the seat of the avalanche phenomenon.
