Abstract
Abstract A support designed for hybrid optoelectronics, including at least one integrated optical guide and including a substrate on which the optical guide has been created by depositing a suitable material on the substrate to create a lower confinement layer, a guide core layer, and an upper confinement layer. The optical guide is designed to be optically connected to an optoelectronic component mounted on the support, in which the support positions the component to ensure its optical alignment with the optical guide. The support includes abutments located at the core level, or defined in a confinement layer in relation to the core layer, to ensure the vertical positioning of the component. The invention also relates to processes for producing the support.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A support for use in the field of hybrid optoelectronics comprising at least one integrated optical guide and including a substrate on which the optical guide is created by applying a deposit of a suitable material to the substrate to create a lower confinement layer, a guide core layer and an upper confinement layer, the optical guide being designed to be optically connected to an optoelectronic component mounted on the support, the support comprising means for positioning the component to ensure its optical alignment with the optical guide, said positioning means comprising abutments to ensure the vertical positioning of the component, wherein said abutments are located at one of the following levels: the top of the core layer, an intermediate plane between the bottom of the core layer and its top, the top of the lower confinement layer, and an intermediate plane within the lower confinement layer, and wherein the abutments are independent from the upper confinement layer.
