GUIDING STRUCTURE FOR TRANSFORMING A GAUSSIAN PROFILE PROPAGATION MODE INTO AN EXTENDED PROFILE PROPAGATION MODE

摘要

P The invention proposes a guiding structure making it possible to transform a light wave having at least one central wavelength lambda1 of profile propagation mode of the Gaussian type, resulting from introduction means, into a profile propagation mode of enlarged type, this structure comprising: - a first guiding part (1), and - a second part (2), comprising at least one microguide (3), one end (5) of which has a Y shape, the first and the second part as well as the introduction means are combined together so that when the light wave is introduced into the first part or the second part, it is transformed in the other part into an enlarged profile for the length lambda1 central wave. The invention applies to the production of numerous optical components and in particular to multiplexers and demultiplexers. /P
