Abstract
(EN)
Provided is an optical semiconductor device comprising a laser oscillator on a semiconductor substrate and an optical modulator on the semiconductor substrate. The laser oscillator has a loop mirror on at least one of a pair of reflecting mirrors. The loop mirror has a loop waveguide and a plurality of first ring resonators that are inserted in series in the loop waveguide. The optical modulator has a plurality of second ring resonators that are connected in cascade along a modulator waveguide. The width of the transmission band of the first ring resonator is set to be wider than the width of the transmission band of the second ring resonator.

L'invention concerne un dispositif semi-conducteur optique comprenant, d'une part un oscillateur laser implanté sur un substrat semi-conducteur, et d'autre part un modulateur optique implanté sur ce même substrat semi-conducteur. L'oscillateur laser comporte un miroir-boucle équipant l'un au moins des réflecteurs d'une paire de réflecteurs. Le miroir-boucle comporte un guide d'ondes bouclé et une pluralité de premiers résonateurs annulaires insérés en série dans le guide d'ondes bouclé. Le modulateur optique comporte une pluralité de seconds résonateurs annulaires placés en cascade le long d'un guide d'ondes du modulateur. La largeur de la bande d'émission du premier résonateur annulaire est définie de façon à être supérieure à la largeur de la bande d'émission du second résonateur annulaire.
