CA 2398827

A single-mode semiconductor diode laser includes a single-mode section (201), a tapered mode-transformer section (202) coupled to the single-mode section (201), and a power-supply section (203) coupled to the tapered mode transformer section (202). The power-supply section (203) has a width larger than the width of the single-mode section (201). The tapered mode-transformer section (202) is characterized in that optical energy from said single-mode section (201) adiabatically couples to the power-supply section (203) through the mode-transformer section (202).

Un laser de diode de semi-conducteur à mode unique comprend une section à mode unique (201), une section de transformateur à mode conique (202) couplée à ladite section à mode unique (201), et une section d'alimentation (203) couplée à ladite section de transformateur à mode conique (202). La section d'alimentation (203) présente une largeur plus importante que la largeur de la section à mode unique (201). La section du transformateur à mode conique (202) est caractérisée en ce que l'énergie optique provenant de ladite section à mode unique (201) est couplée adiabatiquement à la section d'alimentation (203) par l'intermédiaire du transformateur de mode (202).
