Title (EN) TUNABLE LASER DEVICE
(FR) DISPOSITIF LASER ACCORDABLE
Abstract:
(EN) A tunable laser device comprises a multi-section distributed feedback (DFB) laser having : - a first Bragg section (3) comprising a waveguide (6) and a Bragg grating, - a second Bragg section comprising a waveguide and a Bragg grating, - a phase section (2) being longitudinally located between the first Bragg section and the second Bragg section, the phase section being made of a passive material, each Bragg section having a first longitudinal end joining the phase section and a second longitudinal end opposed to the phase section, wherein the Bragg grating of at least one Bragg section has a grating coupling coefficient which decreases from the first longitudinal end to the second longitudinal end of said at least one Bragg section.
(FR) L'invention concerne un dispositif laser accordable qui comprend un laser à rétroaction distribuée (DFB) multi-sections comportant : - une première section de Bragg (3) comprenant un guide d'ondes (6) et un réseau de Bragg, - une seconde section de Bragg comprenant un guide d'ondes et un réseau de Bragg, - une section de phase (2) longitudinalement située entre la première section de Bragg et la seconde section de Bragg, la section de phase étant faite d'un matériau passif, chaque section de Bragg ayant une première extrémité longitudinale jointe à la section de phase et une seconde extrémité longitudinale opposée à la section de phase. Le réseau de Bragg d'au moins une section de Bragg possède un coefficient de couplage de réseau qui décroît de la première extrémité longitudinale à la seconde extrémité longitudinale de ladite au moins une section de Bragg.
