GUIDE STRUCTURE FOR TRANSFORMATION OF THE MODE OF PROPAGATION FROM A GAUSSIAN TYPE PROFILE INTO A MODE OF PROPAGATION WITH A WIDEBAND PROFILE

摘要

The invention relates to a guide structure for transforming a light wave with at least one central wavelength lambda i and a gaussian propagation profile, emanating from an injection means, into a wideband propagation mode, said structure comprising: a first guide piece (1), a second piece (2), comprising at least one microguide (3), one end (5) of which has a Y form. The first and second piece and the injection means are combined together in such a way that the light wave is injected into the first piece or the second piece and transformed in the other piece into a wideband profile for the central wavelength lambda i. The invention finds application in the production of numerous optical components, in particular, multiplexers and demultiplexers.
