Abstract:
The invention relates to a detection device using at least one transistor (2) with a vertical channel, comprising a mechanical structure (14), free to move relative to the transistor, in a plane containing the transistor drain (10), source (8) and channel (12).
Abstract:
An optical device comprising an optical guide structure (10) for at least one optical beam (11), a mobile optical element (20) designed to interact or not interact with the optical beam using optical element displacement means (40), a flexible support (21) connecting the optical element to the optical guide structure. The device comprises a device (30) for positioning the optical element with respect to the optical guide structure, comprising a first mechanical reference (30.1) connected to the optical guide structure and a second mechanical reference (30.2) connected to the mobile optical element, and means (30.3) of crossconnecting the second mechanical reference and the first mechanical reference, this crossconnection enabling movement of the optical element according to at least one plane containing the first and second mechanical references (30.1, 30.2) and the optical guide structure (10). Use particularly in optical communications.
Abstract:
A structure for separating and prepositioning a set of fibers, and a device designed to contain a set of separate fibers prepositioned using the structure. The separation and prepositioning structure includes at least one recess to contain and preposition a single fiber. The recess includes a bottom wall, a top wall, and at least one side wall formed by the side wall of a pattern with a front edge that is oblique with respect to the bottom wall of the recess. At least one inclined connection surface connects the oblique front edge to the rest of the side wall. The structure and device are applicable particularly to the alignment of optical fibers with microguides contained in an optical device.
Abstract:
Optomechanical device comprising in an integrated optics guiding structure, a fixed part and a mobile part, which is connected to the fixed part, said mobile part being located between i output microguides formed in the fixed part and j input microguides also formed in the fixed part, characterized in that the mobile part comprises a mass, which is only connected by fixing arms to the fixed part, so as to permit the displacement of the mass in a first direction, said mass having k microguides to permit the switching of a light beam from one of the j input microguides to one of the i output microguides.
