Abstract
UN MODULADOR FABRY-PEROT (FP) ASIMETRICO INCLUYE UNA ESTRUCTURA DE CAVIDAD CUANTICA CON CAVIDADES MAS ANCHAS (APROXIMADAMENTE 150ARMSTRONGS) DE LO NORMAL (UNOS 100 ARMSTRONGS). LA CAVIDAD FP TIENE UNA RESONANCIA A UNA LONGITUD DE ONDA DE ABSORCION MAXIMA EXCITONICA DE LA ESTRUCTURA DE LA CC. AUNQUE EL CAMBIO MAXIMO EN LA ABSORCION POLARIZADA ES INFERIOR CON CAVIDADES DE 150 ARMSTRONGS QUE CON CAVIDADES DE 100 ARMSTRONGS, LAS CARACTERISTICAS DE LA ELECTROABSORCION TAMBIEN SE ALTERAN, CON EL RESULTADO DE QUE SE PRODUCEN LOS CAMBIOS MAYORES A LA LONGITUD DE ONDA DEL EXCITON DE BORDE DE BANDA EL-HHL A POLARIZACION NULA. LA ABSORCION SE PUEDE REDUCIR POLARIZANDO LA CC Y, POR LO TANTO, EL MFPA PUEDE TENER UNA CARACTERISTICA QUE ES NORMALMENTE OFF (POLARIZACION NULA, REFLECTIVIDAD NULA). UN DISPOSITIVO TAL PERMITE UNA MODULACION MAS ALTA DEL CONTRASTE Y/O TENSIONES DE FUNCIONAMIENTO INFERIORES. EL MODULADOR FP SE PUEDEN UTILIZAR EN SEEDS.
