Latest Patents

Drouart holds a patent for an "Optical waveguide fabrication method." This method involves creating an optical waveguide that consists of a plane substrate made from a material with a relatively low refractive index. The design includes a light propagation layer with a higher refractive index, sandwiched between two strips of lower refractive index material. Additionally, a light confining layer is incorporated, which also has a lower refractive index than the propagation layer. The unique aspect of this method is that at least one of the layers is produced by circulating vapors of silicon compounds in a silica tube, which are then heated to deposit a layer of doped silica. This process allows for modifications to the refractive indices through various techniques, enhancing the functionality of the optical waveguide.
