Abstract
An optoelectronic device having an optical guide and photodetector integrated on a common substrate is provided with a light coupling means for increasing the absorption of light within the photodetector. This means consists of freeing the lower portion of the guide layer--opposite the photodetector--to bring it into contact with air. The use of air has the effect of repelling the light propagating through the guide layer towards the absorbent layer of the photodetector thereby increasing the photodetector efficiency.
