The invention relates to a method for treating a silicate-type glass comprising alkali and alkaline-earth metal oxides or dor IIIA metal oxides, said method comprising at least the following steps: (a) incorporation of nitrogen into the surface of the glass; and (b) thermal poling treatment of the material obtained in (a), under a chemically inert controlled atmosphere. The invention also relates to the material produced by said method.

Method for treating vitreous materials by thermal poling

A device for inducing by thermal poling a spatially controlled refractive index gradient inside at least one amorphous inorganic material to be treated, includes a structured electrode arranged on the surface or in proximity to the surface of the material to be treated; and at least one dielectric material. The structured electrode includes at least one conductive zone and at least one non-conductive zone and it is confined between the amorphous inorganic material to be treated and the dielectric material.

Device and method for inducing by thermal poling a spatially controlled refractive index gradient inside an amorphous inorganic material

A method for the inscription of second-order nonlinear optical properties on a support including an amorphous material, the method including: heating the support within a temperature range allowing the movement of charges inside the support; applying a structured electrode to the support, generating an electrical field designed to induce the formation of non-linear optical properties on the surface of the support; and cooling the support.

Method for the inscription of second-order nonlinear optical properties into an amorphous or vitreous material

Optical fiber () made of a photosensitive glass and with a rectangular cross section, wherein the radius of curvature of a corner of the rectangular cross section is smaller than 100 microns.

Ribbon optical fiber made of photosensitive glass

A method for 3D recording of data on a medium formed from a transparent photosensitive material including at least one dopant. The method includes a first step of calibrating and checking a pulsed light source including calibrating the number of pulses, the level of fluence of each pulse emitted and the rate of the pulses and a step of inscribing an area of the material. The fluence of each pulse emitted, the number of pulses and the rate of the pulses are suitable for irradiating the material in the area so as to form fluorescent clusters stabilized from the dopant while minimizing the modification of the refractive index and the absorption coefficient of the medium in a wavelength range from visible to near infrared.

Method for writing and reading data by fluorescence on a light-sensitive substrate, and related substrate and devices

The present invention relates to novel vitroceramic or lens compositions that are nanostructured and transparent or translucent, including at least 97%, such as 97% to 100%, preferably 99% to 100%, by weight, relative to the total weight of the material, of a composition having the following formula I: (GeO)(SiO)(BO)(GaO)(Oxy)(Oxy)(I) where Oxyis an oxide selected from ZnO, MgO, NbO, WO, NiO, SnO, TiO, BiO, AgO, CaO, MnO, or a mixture thereof, selected preferably from ZnO, MgO, NbO, WO, NiO, SnO, AgO, CaO, MnO, or a mixture thereof, selected more preferably from ZnO, MgO, AgO, BiO, NbO, Or a mixture thereof, selected most preferably from ZnO, MgO, AgO, NbO, or a mixture thereof, and Oxyis an oxide selected from NaO, KO or a mixture thereof, Oxyis preferably NaO, and x, y, z, a, b and k are as defined in claim, to the manufacturing method thereof and to the uses thereof in the field of optics.

Nanostructured glasses and vitroceramics that are transparent in visible and infra-red ranges

The invention relates to novel transparent glasses, vitroceramics, and transparent or translucent ceramics containing, in relation to the total composition of the glass, vitroceramic, or ceramic, at least 60 wt % of a composition having the following formula (I): (M1O)x(M2O)y(M3)2O3)z(Al2O3)100&#x2212;x&#x2212;y&#x2212;z (I), where M1 is an element selected from among Ba and/or Sr, M2 is an element selected from among Mg or Ca, x and y are numbers such that 30&#x2266;x+y&#x2266;80, y is between 0% and 10% of x, M3 is an element selected from among B, Ga, or In, and z is a number between 0% and 10% of (100&#x2212;x&#x2212;y). The invention also relates to the method for manufacturing said compositions and to the uses of said compositions in the field of optics.
