Une étude théorique sur les diodes laser DFB déphasées à haut rendement en pente est présentée. Nous avons proposé une nouvelle structure de réseau appelée réseau à modulation de pas asymétrique (APM), et calculé son efficacité de pente et son rendement monomode. Afin de prendre en compte la période de réseau modulée ; nous avons développé une matrice F qui comprend directement une structure de réseau gazéifiée. Les diodes laser DFB déphasées APM sont constituées d'un réseau uniforme dans une moitié de la cavité et d'un réseau crénelé dans l'autre moitié. Cette structure provoque une distribution asymétrique du champ à l’intérieur de la cavité et la puissance de sortie optique d’une facette est supérieure à celle de l’autre facette. Selon les résultats de la simulation, lorsque le coefficient de couplage normalisé κ L est de 3.0, le rapport de puissance de sortie avant/arrière est de 2.6, tandis que le rendement monomode reste à 100 %, et simultanément l'amélioration du rendement en pente devient de 65 %. meilleur que celui des lasers DFB déphasés quart d'onde ordinaires de même valeur κ L.

Abstract: A theoretical study on high slope-efficiency phase-shifted DFB laser diodes is presented. We have proposed a new grating structure called asymmetrically-pitch-modulated (APM) grating, and calculated its slope- efficiency and single-mode-yield. In order to take into account the modulated grating period; we have developed an F-matrix which directly includes a chirped grating structure. APM phase-shifted DFB laser diodes consist of a uniform grating in one half section of the cavity and a chirped grating in the other half. This structure causes asymmetrical field distribution inside the cavity and the optical output power from one facet is larger than that from the other facet. According to the simulation results, when the normalized coupling coefficient κ L is 3.0, the front-to-rear output power ratio is 2.6, while the single-mode-yield remains at 100%, and simultaneously the slope-efficiency improvement becomes 65% better than that of ordinary quarter-wave phase-shifted DFB lasers of the same κ L value.
