Abstract: An integrated circuit chip cooling device includes a network of micropipes. A first pipe portion and a second pipe portion of the network are connected by at least one valve. The valve is formed of a bilayer strip. In response to change in temperature, the shape of the bilayer strip changes to move the valve from a substantially closed position to an open position. In one configuration, the change is irreversible. In another configuration, the change is reversible in response to an opposite change in temperature.

Abstract: A power conversion device includes an enclosure containing one or more drops of a liquid. A capacitive electret transducer is coupled to the enclosure. In response to applied heat at a heating surface, the liquid vaporizes and then condenses on a flexible membrane of the capacitive electret transducer. The flexible membrane is displaced in response to the vaporization-condensation and the capacitive electret transducer generates an output current.

Abstract: A light sensor includes a semiconductor substrate supporting a number of pixels. Each pixel includes a photoconversion zone extending in the substrate between a front face and a back face of the substrate. An optical diffraction grating is arranged over the back face of the substrate at a position facing the photoconversion zone of the pixel. For at least two different pixels of the light sensor, the optical diffraction gratings have different pitches. Additionally, the optical grating of each pixel is surrounded by an opaque wall configured to absorb at operating wavelengths of the sensor.

Abstract: An electro-optical phase modulator includes a waveguide made from a stack of strips. The stack includes a first strip made of a doped semiconductor material of a first conductivity type, a second strip made of a conductive material or of a doped semiconductor material of a second conductivity type, and a third strip made of a doped semiconductor material of the first conductivity type. The second strip is separated from the first strip by a first interface layer made of a dielectric material, and the third strip is separated from the second strip by a second interface layer made of a dielectric material.
