Claim 11:
12. A method for manufacturing the optical particle detector according to claim 1, comprising:
providing a substrate;
forming the optical waveguide by implanting ions into the substrate;
forming the channel by drilling into the substrate at least at the optical waveguide, such that said channel crosses the optical waveguide, the optical waveguide thus comprising at least a first part and a second part separated from one another by the channel, the first part of the waveguide having a first entrance and a first exit opening out onto the channel and the second part of the waveguide having a second entrance and a second exit opening out onto the channel, said first and second parts being arranged in such a way that the first entrance faces the second exit and the second entrance faces the first exit;
providing a plurality of photodetectors; and
assembling the photodetectors of said plurality with the substrate, by disposing the photodetectors at least partially around the channel.
