Abstract
The device comprises microguides (G1, G2, . . . GN) traversed by light beams with N different wavelengths, a diffraction grating (R) formed by reflecting elliptical facets and a single microguide (G). Point (S) of the end of the single microguide (G) and points (P1, . . . PN) of the ends of microguides (G1, . . . GN) are optically joined by the grating for different wavelengths.
