Patent CA-2635303-A1 (CA)
Title: Engineered structure for solid-state light emitters
Inventor: HILL E STEVEN
IPC: H01L29/12
Filed: 2006-12-22
Abstract: An engineered structure of a light emitting device comprises multiple layers of alternating active and buffer materials disposed between AC or DC  electrodes, which generate an electric field. The active layers comprise luminescent centers, e.g. group IV semiconductor nanocrystals, in a host matrix, e.g. a wide bandgap semiconductor or dielectric material such as silicon dioxide or silicon nitride. The buffer layers are comprised of a wide bandgap semiconductor or dielectric material, and designed with a thickness, in the direction of an applied electric field, that ensures that electrons passing therethrough picks up enough energy to excite the luminescent centers in the adjacent active layer at an excitation energy to emit light efficiently at a desired wavelength.
Patent CA-2636481-A1 (CA)
Inventor: IWATA HIROKAZU
IPC: H03C1/06
Filed: 2008-06-27
Abstract: Un émetteur AM (modulation d'amplitude) capable d'améliorer la distorsion de modulation est présenté. Un sommateur ajoute un signal de modulation à un signal de référence de puissance préétabli. Un amplificateur APC (commande automatique de puissance) compare un niveau d'un signal de détection produit par le filtre passe-bas à un niveau d'un signal du sommateur. L'amplificateur APC, en fonction du résultat de la comparaison, génère un signal de contrôle de gain qui fait une différence entre un niveau du signal de détection et un niveau du signal proche de zéro et envoie le signal de contrôle de gain à un amplificateur de puissance. L'amplificateur de puissance module le signal produit à partir de l'amplificateur par le signal de contrôle de gain et amplifie la puissance du signal modulé en fonction d'un niveau du signal de contrôle de gain. Puisque l'amplificateur APC envoie le signal de contrôle de gain à l'amplificateur de puissance, un degré de modulation ne dépend pas d'une caractéristique de distorsion non linéaire de l'amplificateur de puissance.
