Various embodiments may provide an optical fiber for sensing an analyte. The optical fiber may include a dielectric core wall defining a hollow space. The optical fiber may also include a cladding layer surrounding the dielectric core wall and spaced apart from the dielectric core wall. The optical fiber may further include a plurality of supports extending from the cladding layer to the dielectric core wall. A thickness of the dielectric core wall may be greater than a thickness of each of the plurality of supports. The dielectric core wall may be configured to carry an optical light for sensing the analyte.

Optical element and associated manufacturing method

A device for producing a polychromatic light including an optical pump that delivers a first radiation at a first wavelength; a light guide; and a selective injector that injects the radiation into the guide, the guide being arranged to generate a harmonic corresponding to the selected injector and provide a polychromatic light at an outlet, by non-linear excitation of the first radiation and the harmonic.

An optical module for chromatic dispersion compensation comprises an optical fiber wound so as to present a variable radius of curvature. The fiber has an index profile such that it has, for the main propagation mode, a negative dispersion value having a minimum at a given wavelength in a given spectral band. The value and the spectral position of the dispersion minimum vary with the radius of curvature of the fiber. The module allows the introduction of a large chromatic dispersion compensation value overall of a given spectral band, as well as compensation corrections for specific wavelengths inside the given spectral band.
