Abstract
The invention relates to a sampling device comprising in a substrate (15), a wave guide core (17) capable of transporting a light wave E and an optical cladding (19), at least one portion of the cladding surrounding at least one portion of the core in a zone called the zone of interaction (I), the said zone comprising among others a grating (21) capable of coupling in the cladding, part of the light wave, the coupled part being called the coupled wave C, the refractive index of the cladding being different to the refractive index of the substrate and lower than the refractive index of the core at least in the part of the cladding next to the core in the zone of interaction. The cladding of the device is advantageously connected to a recovery and treatment element (33) for all or part of the coupled wave (C).
