Abstract: An optical coupling device including, in sequence, a focusing lens and an optical coupling network, the coupling device being symmetric with respect to a plane, the focusing lens formed in a core layer, as a front face, perpendicular to the plane, the optical coupling network including a plurality of trenches, formed on the front face, and convex in shape, the optical coupling network including, in sequence, a first sub-network and a contiguous second sub-network, respectively delimited, by a first contour and a second contour, the first and second contours extending in a divergent manner and convergent manner respectively.

Abstract: The invention relates to a process for producing a thermogenerator (10) comprising a plurality of thermocouples formed of p-type thermoelements (12) and n-type thermoelements (14). A wafer (18), provided with a plurality of holes (20a, 20b) is covered in thermoelectric material powder (22, 24). Pressure (P) is applied to the powder (22, 24) so that it penetrates into the holes (20a, 20b) while heating so as to form a plurality of p-type and n-type thermoelements (12, 14) contained in the wafer (18). The wafer (18) is thinned, the thinned wafer thus forming a matrix (16) in which the thermoelements (12, 14) are contained. While preserving the matrix (16) the p-type thermoelements are connected so as to form thermocouples and the n-type thermoelements are connected so as to form thermocouples, thereby obtaining a thermogenerator (10).
