Abstract (en)
[origin: FR2770911A1] The invention concerns an optical device with waveguide (1) for transferring electromagnetic energy in the form of a radiation beam (I) whose wavelength can be in the range of visible light and near infrared radiation, comprising a waveguide (1) extending between an input medium (2) and an output medium (3), having a material transparent structure with respect to the transmitted radiation and elongated in the radiation propagation direction (Z). The invention is characterised in that the waveguide (1) material structure has a maximum transverse dimension (Do), in the incident radiation beam (I) plane, which is less than half the wavelength lambda of the incident beam (I), the waveguide (I) material structure has inhomogeneities in the optical refractive index in the radiation propagation direction (Z) and the transferred radiation is collected at a submicronic distance from the optical device waveguide (1) output surface (3<u>a</u>).
