Title (EN) A TUNABLE OPTICAL OSCILLATOR
(FR) OSCILLATEUR OPTIQUE ACCORDABLE
Abstract: front page image
(EN)An optical oscillator has first (13) and second (14) resonant cavities with at least a portion of each cavity sharing a common volume. A characteristic of at least one of the cavities is variable. A non-linear material (20) is positioned within the 'common volume'. Variation of the or each resonant cavity enables a continuously tunable output signal to be obtained. The invention overcomes the problem associated with prior art systems in which phase matching, resonance of a common cavity at two wavelengths and energy conservation were required simultaneously.
(FR)Un oscillateur optique possède des première (13) et seconde (14) cavités résonnantes, au moins une partie de chaque cavité utilisant en commun un volume. Une caractéristique d'au moins une de ces cavités est variable. Un matériau non linéaire (20) est placé à l'intérieur du 'volume commun'. La variation de la cavité ou de chaque cavité résonnante permet d'obtenir un signal de sortie accordable de façon continue. L'invention résout le problème relatif aux systèmes de la technique antérieure dans lesquels la concordance de phase, la résonnance d'une cavité commune à deux longueurs d'ondes et la conservation d'énergie étaient simultanément requises.
