ABSTRACT:
Optoelectronic device integrating a photodetector having two diodes arranged side by side, constructed from layers of semiconductor material on a substrate that also incorporates a light guide for directing light to the diodes. The two identical, juxtaposed diodes (D1, D2) are arranged head to tail. The diode ensuring the photodetection is that which is reverse biased.
