The invention relates to a spectrograph () comprising a waveguide () provided with accesses (), a means for injecting two guided contra-propagative waves by each accesses in such a way that a spatial interference is formed in the waveguide, means () for detecting the energy of the evanescent wave of the guided field produced by the interference of said contra-propagative waves.

Contra-propagative wave spectograph

An interferential spectroscopy detector including a waveguide having an input side and a mirror on an opposite side, and means for detecting electromagnetic rays delivering an electric signal as a function of local intensity of an electromagnetic wave, detection being produced between an input side and the mirror.

Interferential spectroscopy detector and camera

The integrated-optics coupling component is designed to cooperate with a transverse multimode power laser diode () with semi-conductor to form a transverse multimode power laser. It comprises an input zone () connected to at least one output waveguide () by at least two adiabatic tapering zones (). At least two filtering windows () form the inputs of the adiabatic tapering zones () at the end of a diffraction zone defined by the input zone. Reflecting elements, for example a Bragg grating (), can be arranged on the output waveguide. An emitting face () being antiglare-treated, an extended laser cavity oscillating on a single predetermined mode is thus defined between a reflecting rear face () of the laser diode and the reflecting elements ().

The component comprises structures, achieved in integrated optics, exerting predetermined stresses on a light wave guiding waveguide so as to maintain or modify in predetermined manner the polarization state of an incident light wave. These structures are formed by at least one segmented plane waveguide arranged laterally with respect to the light wave guiding waveguide and formed by parallel lateral waveguides perpendicular to the longitudinal axis of the light wave guiding waveguide. These structures are achieved at the same time as the light wave guiding waveguide, the segmented plane waveguides having refractive indexes lower than or equal to those of the light wave guiding waveguide. Such structures can be arranged symmetrically or asymmetrically, alternately on each side of the light wave guiding waveguide.

Integrated optics component with polarization effect

A Pockels-effect electro-optical modulator including a light guide having a core made of an inorganic amorphous material, and on which a structure is superposed that is made up of two electrode-forming layers between which an electro-optical polymer is interposed, said modulator being characterized in that said structure is superposed directly on the material of the core of the light guide. The transitions between the active and passive zones are advantageously adapted to minimize losses.
