Abstract
DISPOSITIVO MULTIPLEXADOR EN LONGITUD DE ONDA MEDIANTE UN INTERFEROMETRO MACH-ZEHNDER Y UN DIVISOR ASIMETRICO. ES UN COMPONENTE OPTICO PASIVO FORMADO MEDIANTE UNAS GUIAS DE ONDA Y APLICABLE EN EL CAMPO DE LA OPTICA INTEGRADA, FABRICANDOSE MEDIANTE TECNOLOGIA PLANAR, Y QUE OFRECE UN NUEVO SISTEMA DE MULTIPLEXACION O DE DEMULTIPLEXACION EN LONGITUD DE ONDA, BASADO EN EL EFECTO COMBINADO DE UN INTERFEROMETRO MACH-ZEHNDER (1, 2 Y 3) COMO CONVERSOR SELECTIVO DE MODO Y UN DIVISOR ASIMETRICO (5) COMO SEPARADOR DE MODOS. CUENTA CON UN DIVISOR ACROMATICO 3 DB EN FORMA DE Y (1) QUE DIVIDE DOS SEÑALES DE ENTRADA CON DIFERENTES LONGITUDES DE ONDA, PARA LLEVARLAS A UNOS BRAZOS (2) DE DISTINTAS ANCHURAS (WSI1 SC Y WSI2 SC) DEL INTERFEROMETRO MACH-ZEHNDER (1, 2 Y 3), DONDE LAS SEÑALES ADQUIEREN UN DESFASE RELATIVO DE 0 Y 180G PARA CADA LONGITUD DE ONDA, TRAS LO CUAL PASAN A UN RECOMBINADOR (3) QUE CONECTA CON UNA GUIA BIMODO (4), A CUYOS DISTINTOS MODOS SE ACOPLAN LAS DISTINTAS LONGITUDES DE ONDA, SIENDODIRECCIONADOS DICHOS MODOS MEDIANTE DOS RAMAS DE DIFERENTES ANCHURAS DEL DIVISOR ASIMETRICO (5), PRODUCIENDOSE ASI EL EFECTO DE DEMULTIPLEXACION.
