  • Patent number: 8620119
    Abstract: The invention relates to an array of waveguides (1) comprising a set of coupled waveguides that are substantially parallel and oriented in a guidance direction (Y), the set of waveguides comprising a first zone (2) formed by waveguides coupled according to a first coupling coefficient, and a second zone (3) formed by waveguides coupled according to a second coupling coefficient that is different from the first coupling coefficient, characterized in that the second coupling coefficient is different from the first coupling coefficient in the guidance direction and in the direction (X) perpendicular to the guidance direction.

  • Patent number: 5946438
    Abstract: The present invention relates to a device for both-way transposition between optical signals and electrical signals, for a communications system, said device comprising a vertically integrated component comprising an optically driven oscillator based on a negative differential conductance mechanism, for performing optical-to-millimetric conversion on the down path, and an asymmetric Fabry-Perot cavity modulator for performing the electrical-to-optical conversion function on the up path.

  • Patent number: 5703379
    Abstract: The present invention relates to a light-controlled semiconductor heterostructure component for generating microwave frequency oscillations, wherein the heterostructure comprises at least two semiconductor materials: at least one of them absorbing light by creating electron-hole pairs; and the other one of them having majority carriers with a relationship of velocity as a function of electric field that presents a region of negative slope.

  • Patent number: 5397889
    Abstract: Guided-wave photoreceptor based on quantum wells made of semiconductor materials, particularly for coherent communications system with polarization diversity.This photoreceptor has at least one pair composed of a first photodetector (76) and a second photodetector (78). At least the first photodetector is formed on a semiconductor substrate (94) and has a multilayer ribbon with multiple quantum wells made of semiconductor material (100); this multilayer ribbon is provided to guide an incident light; the first photodetector is capable of absorbing the transverse magnetic component of that light, whose electrical field has a component perpendicular to the plane of the multilayer; the transverse electrical component of that light is virtually not absorbed in the first photodetector; the second photodetector is provided to absorb this transverse electrical component.
