Abstract[English]
A waveguide structure includes a plurality of alternating segments of normal dispersion (ND) waveguide segments and anomalous dispersion (AD) waveguide segments along a length of the waveguide structure. The alternating segments are configured such that supercontinuum generation (SCG) of optical pulses traversing the waveguide structure is affected in the ND waveguide segments and the AD waveguide segments. The AD waveguide segments are each further configured to shape the optical pulses into higher-order soliton pulses that are compressed to a soliton inversion point to thereby cause a temporal width and a spectral width of the higher-order soliton pulses to oscillate between maximum and minimum values as the higher-order optical pulses traverse each of the AD waveguide segments.[French]
Une structure de guide d'ondes comprend une pluralité de segments qui alternent entre des segments de guide d'ondes à dispersion normale (DN) et des segments de guide d'ondes à dispersion anormale (DA) le long d'une longueur de la structure de guide d'ondes. Les segments alternés sont conçus de telle sorte que la génération de supercontinuum (SCG) des impulsions optiques qui traversent la structure de guide d'ondes est affectée dans les segments de guide d'ondes DN et dans les segments de guide d'ondes DA. Chacun des segments de guide d'ondes DA est également conçu pour mettre en forme les impulsions optiques de façon à les transformer en impulsions de soliton d'ordre supérieur qui sont compressées jusqu'à un point d'inversion de soliton pour ainsi amener une largeur temporelle et une largeur spectrale des impulsions de soliton d'ordre supérieur à osciller entre des valeurs maximale et minimale lorsque les impulsions optiques d'ordre supérieur traversent chacun des segments de guide d'ondes DA.
