Disclosed is a hybrid simulator for teaching optics or for training adjustment of an optical device. The hybrid simulator includes at least one dummy optical component physically simulating an optical device, at least one actuator device for generating or simulating an adjustment of the dummy optical component, a sensor configured for detecting an adjustment signal representative of operating the actuator device, a digital processing system including a numerical model for simulating an output numerical optical beam resulting from interaction between an input numerical optical beam and a numerical optical component representing the optical device as a function of the adjustment signal and a display system for displaying a visual signal representative of the output optical beam and/or augmented reality signals.

Hybrid simulator and method for teaching optics or for training adjustment of an optical device

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.

This invention relates to a wide band optical gate in the terahertz domain (wavelengths in the far infrared). It comprises a first optical source () emitting a first beam (FTHz) in said terahertz domain, a first plate made of a semiconducting material () illuminated by said terahertz beam and a second optical source () emitting a second beam (FIR) at a wavelength capable of saturating the first plate () made of a semi-conducting material and making it reflective at terahertz wavelengths. This invention also relates to a system for measuring terahertz signals and to a terahertz generator. It is particularly applicable to systems for measuring terahertz signals and to terahertz generators.
