Title
(EN) WAVELENGTH-SWEPT LIGHT SOURCE
(FR) SOURCE DE LUMIÈRE À BALAYAGE DE LONGUEUR D'ONDE
Abstract
(EN)
A wavelength-swept optical source is based upon a combination of a coherent source of ultra-short optical pulses, doped fiber amplifier, and specialized dispersive optical medium to create time-stretched pulses. The pulses are broadened to have a spectral bandwidth that covers a wavelength range of interest for a particular wavelength sweeping application and are thereafter subjected to time-stretching within the dispersive optical medium so as to sufficiently separate in time a number of wavelength components within each pulse.
(FR)
L'invention concerne une source optique à balayage de longueur d'onde basée sur une combinaison d'une source cohérente d'impulsions optiques ultracourtes, d'un amplificateur à fibre dopée et d'un milieu optique dispersif spécialisé pour créer des impulsions étirées dans le temps. Les impulsions sont élargies pour avoir une largeur de bande spectrale qui couvre une plage de longueurs d'onde d'intérêt à des fins d'application de balayage de longueur d'onde particulière et sont ensuite soumises à un étirement temporel à l'intérieur du milieu optique dispersif de façon à séparer suffisamment dans le temps un certain nombre de composantes de longueur d'onde à l'intérieur de chaque impulsion.
