Optoelectronic unit for receiving optical signals for optical communications has two stacked detectors one with optically active surface of one of these detectors being screened

摘要

The unit has at least two detectors (10',20'), each with an optically active surface (11',21') for converting optical signals into electrical signals. Two detectors are stacked one on top of the other with the optically active surface of one of these detectors being screened and one of the detectors being mounted on a bearer (30').
