Abstract (en)

[origin: US2002131714A1] The invention proposes a guiding structure capable of transforming a lightwave with at least one central wavelength lambdi with a Gaussian type propagation mode profile coming out of the introduction means into a widened type propagation mode profile, this structure comprising: a first guiding part (1), and a second part (2) comprising at least one microguide (3), with one end (5) in the form of a Y, the first and second part and the introduction means are connected to each other such that when the lightwave is introduced into either the first or the second part, it is transformed into the other part into a widened profile for the central wavelength lambdi. The invention is applicable to the manufacture of a large number of optical components, and particularly wavelength multiplexers and demultiplexers.
