摘要：The invention relates to an optical waveguide wavelength multiplexer using evanescent-wave coupling. It compris a first monomode optical guide (2a) at the wavelength lambda 1 and a cond optical guide (2b) guiding the entrant wave of
wavelength lambda 2. The guides have a core and an optical cladding and they converge in an interaction zone. The cores of the first and cond guides, being clo together, define an interaction length and coupling lengths for each wavelength lambda 1, lambda 2. According to the invention, lambda 1 is greater than lambda 2 and the interaction length is equal to the coupling length for lambda 1.
