Abstract

DISPOSITIVO LASER, QUE TIENE UN CUERPO SEMICONDUCTOR QUE COMPRENDE UNA ZONA ACTIVA EN FORMA DE TIRA SITUADA DENTRO DE UN RESONADOR, EN EL CUAL SE RESTRINGE LA REGION EN LA QUE SE PRODUCEN LOS FENOMENOS DE ENVEJECIMIENTO. EL DISPOSITIVO ESTA CONSTITUIDO DE UN SUSTRATO (11) DE ARSENIURO DE GALIO, CONDUCTOR DE TIPO N, DE ESPESOR 100 UM. SOBRE ESTE SUSTRATO (11) SE ENCUENTRA UNA ZONA ACTIVA (7) QUE CONTIENE UN CIERTO NUMERO DE UNIONES SEMICONDUCTORAS P-N. ESTAS ZONAS SEMICONDUCTORAS ESTAN CONECTADAS ELECTRICAMENTE A ELECTRODOS (10), Y TIENEN UNA DIMENSION MAXIMA DE 20 UM. QUE EVITA QUE SE EXTIENDAN LOS DEFECTOS DE RETICULA, PROVOCADORES DEL ENVEJECIMIENTO DEL DISPOSITIVO. EL DISPOSITIVO OFRECE VARIANTES DE REALIZACION.
