  • Optical device as a driving aid
    Patent number: 5504480
    Abstract: The present invention relates to an optical device used as a driving aid. According to the invention, a lidar is formed by a sample of glass doped with erbium and pumped by a fraction of the light flux generated by a xenon discharge lamp with a concentrator. The unit is disposed in a headlamp or other light, optionally making use of their lighting means, and enables a receiver and circuitry generating navigational aid parameters to be activated.

  • Integrated optic waveguide and fabrication method
    Patent number: 5134681
    Abstract: An optic waveguide includes a buffer layer with an index n1, a strip with a high index n2 and a guiding layer with an index n3. The refraction indices correspond to the relationship: n2>n3>n1. The thickness of the strip is chosen to be very small so as to induce no optic losses. The device can be applied to the making of optic and electrooptical components.

  • Integrated electro-optical modulator/commutator with pass-band response
    Patent number: 4969701
    Abstract: A modulator/commutator comprises two optical guide waves coupled to each other on a length and connected to an input guide by a Y junction. Electrodes are associated with each wave guide and enable the application of an interaction field on an interaction length. The optical and electrical waves have different propagation speeds. The interaction length and the coupling length are fixed so that their ratio has a value enabling an optical wave to successively experience the positive and negative alternations of an alternating field applied to the device by the electrodes, thus simulating a multiple-section operation. This device gives 100% efficiency of switching over to either of the two optical guides.

  • Process and device for simultaneously measuring the geometrical characteristics of an optical fibre
    Patent number: 4563087
    Abstract: The invention relates to a process and device for measuring the optical core - mechanical sheath concentricity and the optical core ellipticity of an optical fibre. The process consists of injecting a light beam into a fibre, which has been previously bared at one of its ends. The analysis of the near field of this fibre by a detector performing a relative rotary movement with respect to said fibre provides details on the core - sheath concentricity and the core ellipticity, by carrying out a narrow band detection at the rotational frequency and at double its frequency.

  • Device for providing a drawn fiber-like object with a helical structure
    Patent number: 4509968
    Abstract: The invention relates to a process making it possible to produce a drawn object having a chiralic structure. This production process consists of subjecting the object to torsion during its drawing and simultaneously to hardening making it possible to fix part of the thus obtained torsional stresses in the structure.
