    Abstract: The present invention concerns a procedure for controlling a radiation source which has been implemented with the aid of light-emitting diodes, or LEDs, from the radiation produced by them being separated the desired wavelength range, of which the intensity is controlled or maintained constant. The radiation source is implemented by means of a LED row (2) formed of semiconductor chips, or LED elements, (21, 22, 23,..., 26), from the radiation of which is separated a wavelength range (DELTAlambda1, DELTAlambda2,...) depending on the location of the LED element in said arrays with an optical means dispersing the radiation to a spectrum, and the intensity of the radiation in this wavelength range, or of the output radiation, is controlled or maintained constant by observing the intensity thereof and regulating with its aid the current passing through the respective LED element. The wavelength ranges of the output radiation are selected electrically by activating a suitable LED element (21, 22, 23,..., 26) in the LED row (2).

    Abstract: A spectrograph usable as a demutiplexer/detector in a wavelength division multiplexing optical system. The spectrograph comprises a planar waveguide (50) and a detector array (52). The planar waveguide (50) has a dispersive edge (56) having an inwardly concave shape, an input edge (62), and a straight output edge (64). The dispersive edge (56) has a reflective diffraction grating (60) formed on it, the grating (60) having a variable line spacing. An optical input signal comprising a plurality of different wavelength ranges enters the waveguide at the input edge (62), and travels through the waveguide and strikes the grating (60). The grating (60) focuses the optical energy in each of the wavelength ranges at a focal spot at the output edge (64), the position of each focal spot being a function of wavelength. The detector array (52) comprises a plurality of photodetectors positioned along a straight line, such that the photodetectors are positioned at the focal spots. Each photodetector therefore detects the optical energy in one of the input ranges. A stack of such planar waveguides may be assembled to form a multi-channel spectrograph.

    Abstract: Un analyseur spectral optique permet de recevoir un faisceau d'entrée (30) par l'intermédiaire d'une fibre optique multimode (28). Le faisceau d'entrée (30) présente une largeur de bande spectrale prédéterminée. Les composantes spectrales individuelles aléatoires du faisceau (30) sont dispersées par une grille (40) afin de générer un spectre (42, 42'...42N). Un détecteur (52) détecte l'ordre de grandeur des éléments dans un spectre focalisé réfléchi (50, 50'...50N) en vue de recueillir les informations placées par un dispositif d'encodage de spectre sur la fibre optique (28) à un endroit éloigné.
