Abstract: A micromonochromator is formed on a substrate and includes a diffraction device (6) associated with an entry that includes at least one entry point and an exit that includes at least one exit point. A mobile arrangement of light guidance (2-20, 4-26) is associated with the entry or the exit or both, and a recovery device (23) is provided by the exit. The mobile arrangement includes at least one mobile beam integrated in the substrate and equipped with at least one light guide. The mobile beam is able to sweep the entry and/or exit in a continuous manner.

Abstract: A positioning system for an optical microstructure (64) in a devise (6) operating under the action of a control means includes a flexible element (63) supporting the optical microstructure and connected to the device. The orientation of the flexible element with respect to the device can be varied under the action of control means in order to put the optical microstructure (64) into at least one determined position. The flexible element is immobilized with respect to the device in order to hold the optical microstructure (64) in the determined position when the control means no longer act.

Abstract: This device comprises a planar input area (4), a planar output area (6), a microguides array (2) laid out between these areas, means (8) of inputting a light beam associated with the input area and means (10) of outputting a light beam associated with the output area. According to the invention, at least two pieces (12, 16, 22) are formed, one comprising one part of at least one of the areas and the corresponding associated means, the other comprising the other part of this area and the other components of the device, and the pieces are added on so as to form the complete device and to adjust the wave length of this device. Application to optical telecommunications and optical spectrometry.

Abstract: The invention relates to an integrated optical device having an optical microguide (44) of index n0 between two media of respective refractive indices n1 and n′1, such that n1<n0 and n′1>n0, and filtering means (46, 48) constituted by at least one reflector element placed on at least one side of the microguide, the reflector elements having at least one element etched in layers of index n1 and/or n′1 and/or n0.

Abstract: A device for the positioning and holding of an optical fiber having a substrate, a groove for receiving the optical fiber, and at least one first and one second groove widenings along a longitudinal axis of said groove. An adhesive substance is introduced in one of the two widenings, said adhesive substance fixing the fiber to the substrate. A process for fixing a fiber to a substrate includes the steps of positioning the fiber, holding said fiber with a tool, and introducing an adhesive substance for fixing the fiber to a substrate.

Abstract: A device is provided for checking the positioning and/or the focusing of a focused light beam. This integrated optical device for checking the positioning and/or the focusing of a focused light beam having an integrated optics guidance structure includes a multimode waveguide or an array of monomode guides distributed so as to be able to exchange energy. The waveguide or monomode guide array is integrated into the guidance structure and is able, when the distribution of the light beam directed at the input of the guide or the array of guides has a single maximum, to transform the distribution into a distribution having N (N.gtoreq.2) maxima at the output of the guide or array of guides. The guideance structure fruther includes a detector for measuring the distribution of the intensity at the output of the waveguide or monomode guide array, and an analyzer for analyzing the intensity distribution connected to the detector.
