Abstract: A device for detection of surface defects on a terminal surface of an optical fiber. The device includes a digital microscope configured to capture an image of a terminal surface; and a mechanism for analyzing the image configured to detect surface defects present on the terminal surface, the analysis mechanism integrating a “U-Net”-type neural network having had its training phase carried out via an enhancer. The enhancer is configured to create training images, intended to train the neural network, based on reference images. The training images are obtained from the reference images by only applying flips, rotations and/or luminosity, contrast, or shade variations to the reference images.

Abstract: The integrated optical component having a glass substrate including integrated optical waveguides wherein the substrate further includes longitudinal grooves at opposite ends of the central portion thereof, which longitudinal grooves are obtained by machining, using the terminal portions of the waveguides extending beyond said central portion as marks for determining the line of machining, together with two transverse grooves on either side of the central portion of the substrate, with the two grooves being separated by a rib whose height is rectified so as to support each fiber to be connected to a waveguide that opens on the same side as the rib.

Abstract: The device includes a first jointing component for joining two fibers to two integrated optic outlet waveguides in the glass substrate, these two fibers are mounted touching one another to constitute a sheet which is itself bonded between two plates of glass, and the spacing of the two corresponding waveguides is equal to the diameter of the fibers, said first jointing component together with its fibers and a second jointing component together with another fiber at the inlet waveguide being bonded against said substrate.
