MULTIPLEXER-DEMULTIPLEXER USING AN ELLIPTICAL CONCAVE GARTING AND PRODUCTED IN INTEGRATED OPTICS

摘要

ABSTRACT OF THE DISCLOSUREThe device comprises microguides (G1, G2,..... GN) traversed by light beams with N differentwavelengths, a diffraction grating (R) formed byreflecting 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 fordifferent wavelengths.
