Title: The Innovations of Maurin Douix
Introduction
Maurin Douix is a notable inventor based in Grenoble, France. He has made significant contributions to the field of image sensors and electro-optic modulators. With a total of 3 patents to his name, Douix continues to push the boundaries of technology.
Latest Patents
One of his latest patents is for a "Backside illumination image sensor and manufacturing method." This integrated sensor features a substrate made of a first semiconductor material with a specific optical refractive index. The substrate includes a pixel array, where each pixel has a photosensitive active zone formed by an index contrast zone. This zone includes a matrix of the first semiconductor material and a periodic structure embedded within it. The periodic structure extends from the backside of the substrate and has a two-dimensional periodicity that correlates with the wavelength of the optical signal. The elements of this structure are made from a second optically transparent material, which has a lower refractive index than the first.
Another significant patent is for an "Integrated electro-optic modulator." This E/O phase modulator includes a waveguide with an insulating substrate, a single-crystal silicon strip, and a polysilicon strip of the same thickness, each doped with opposite conductivity types. An insulating interface layer is positioned between the single-crystal silicon strip and the polysilicon strip. Each strip can be laterally extended, with respective electrical contacts coupled to these extensions.
