Title
(EN) MID-IR MULTIWAVELENGTH CONCATENATED DISTRIBUTED-FEEDBACK LASER WITH AN ACTIVE CORE MADE OF CASCADED STAGES
(FR) LASER À RÉTROACTION RÉPARTIE CONCATÉNÉ MULTI-LONGUEUR D'ONDE À IR MOYENS AVEC UN NOYAU ACTIF FAIT D'ÉTAGES EN CASCADE
Abstract
(EN) Concatenated distributed feedback lasers having multiple laser sections laid out in series are disclosed. The concatenated distributed feedback lasers utilize quantum cascade core designs to produce optical gain in the mid- infrared region and may generate several wavelengths simultaneously or sequentially. Methods of making along with methods of using such devices are also disclosed.
(FR) L'invention concerne des lasers à rétroaction répartie concaténés ayant des sections de laser multiples disposées en série. Les lasers à rétroaction répartie concaténés utilisent des conceptions de noyaux en cascade quantique pour produire un gain optique dans la zone des infrarouges moyens et peuvent générer plusieurs longueurs d'ondes simultanément ou séquentiellement. L'invention concerne aussi des procédés consistant à utiliser de tels dispositifs.
