Abstract:
The invention relates to a process for fitting connectors to optical elements to an integrated optical circuit (26) consisting of connecting at least one optical element to this circuit such that the outputs and/or inputs of each element are located approximately in the same plane (xoz) as the inputs and/or outputs of this integrated optical circuit (26), also located in the same plane (xoz). This process comprises the following steps:the circuit (26) is positioned on a template (35) with patterns that enable subsequent precise alignment of optical elements with inputs and/or outputs of the circuit (26);at least one block (29, 30) capable of holding the optical element(s), is positioned on the template facing the inputs and/or outputs of the circuit (26), and is fixed to the circuit (26);the template is removed, and the optical element(s) is (are) placed in each block (29, 30) the blocks then being aligned with the inputs and/or outputs of the circuit (26).
Abstract:
A method for making a microelectronic device including, on a same substrate, at least one electro-mechanical component including a mobile structure of a monocrystalline semi-conductor material and a mechanism actuating and/or detecting the mobile structure, and with at least one transistor. The method a) provides a substrate including at least one first semi-conducting layer including at least one region in which a channel area of the transistor is provided, b) etches a second semi-conducting layer based on a given semi-conductor material, lying on an insulating layer placed on the first semi-conducting layer, to form at least one pattern of the mobile structure of the component in an area of monocrystalline semi-conductor material of the second semi-conducting layer, and at least one pattern of gate of the transistor on a gate dielectric area located facing the given region.

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.
