Integrated optoelectronic device

摘要

The device has a structure having an SOA type optical amplifier (1) comprising an active zone (3), and a reception photodiode (2) having another active zone (4). The structure has a diluted multimode guide (5) which is common to the optical amplifier and photodiode, where the zones are disposed in order to ensure a coupling of evanescent waves in the active zones. The former zone has a thickness lower than the thickness of the latter zone.
