Mixed silica/polymer active directional coupler, in integrated optics

This invention relates to a directional optical coupler including at least two optical guide cores (26, 28), in silica, lying on a cladding (24) in a mineral dielectric material, and a covering layer (30) in a polymer material, which covers the two optical guide cores, and whose index is less than t...
