Abstract: The invention concerns a method for fabricating at least one detector pixel cell (45) connected to an element (82) formed in a weakly doped silicon substrate (81), characterized in that it comprises: firstly, a first step to fabricate at least one layer (61) by implantation doping and activation annealing, secondly, a second step to fabricate at least one connection node (85) in a circuit (83), from an element (82) formed in the substrate (81) by dry etching and metallization, a step to combine, by bonding, the fabricated doped layer (61) with the fabricated connection node (85); and a step to individualize at least one pixel cell (45) in the doped layer (61) by dry etching; and a passivation and opening step opposite the individualized cell (45), by dry etching. The invention also comprises a sensor including at least one such cell.

Abstract: The present invention relates to a monolithic optical component (400) comprising a light-absorbing layer and a waveguide structure (2). The invention is more particularly adapted to a monolithic component (400) comprising an evanescent coupling photodiode (6) integrated with the waveguide (2). The monolithic optical component (400) comprises a light-absorbing layer and a waveguide (2) evanescently coupled with the light-absorbing layer, the waveguide (2) having one end coupled to an input face (12) of the component to receive an input wave, the 10 component (400) being characterized in that the input face is convex.
