Abstract
METODO Y DISPOSITIVO PARA CONTROLAR UN HAZ LUMINOSO (17) ACOPLADO A UNA CAPA DE TRABAJO (2) DE UN MATERIAL ELECTROOPTICO Y QUE SE DIRIGE A UN AREA DE TRABAJO (16). EN UN PRIMER ESTADO OPTICAMENTE CONDUCTOR, EL AREA DE TRABAJO TIENE UN MODO DE CONDUCCION QUE DIFIERE DEL QUE TIENE EL MATERIAL DE LA CAPA DE TRABAJO CIRCUNDANTE (7), COMO CONSECUENCIA DE LO CUAL APARECEN OTROS INDICES DE REFRACCION; ASI EL AREA DE TRABAJO FORMA UNA GUIA DE ONDAS LUMINOSAS A TRAVES DE LA CUAL ES CONDUCIDO EL HAZ LUMINOSO ACOPLADO (19) A UNA PRIMERA FIBRA DE VIDRIO (22). EN UN SEGUNDO ESTADO OPTICAMENTE CONDUCTOR, EL AREA DE TRABAJO TIENE UN MODO DE CONDUCCION IGUAL AL DEL MATERIAL QUE LO RODEA. DEBIDO A QUE LOS INDICES DE REFRACCION DENTRO Y FUERA DEL AREA DE TRABAJO SON AHORA IGUALES, ESTE AREA DE TRABAJO NO FORMA UNA GUIA DE ONDAS SINO, POR EJEMPLO, UN AISLADOR O REFLECTOR DE LUZ MEDIANTE EL CUAL EL HAZ LUMINOSO ACOPLADO ES CONDUCIDO A UNA SEGUNDA FIBRA DE VIDRIO (21). EL MODO DE CONDUCCION QUASI ESTACIONARIO DEL AREA DE TRABAJO NECESARIO RESPECTIVAMENTE PARA EL PRIMER Y EL SEGUNDO ESTADOS OPTICAMENTE CONDUCTORES SE LOGRA, SUCESIVAMENTE, CALENTANDO EL AREA DE TRABAJO POR ENCIMA DE LA TEMPERATURA DE REBLANDECIMIENTO, EXCITANDO UN CAMPO ELECTRICO EN EL AREA DE TRABAJO Y DEJANDO QUE EL AREA DE TRABAJO SE ENFRIE DE NUEVO. PARA LA CONDUCCION EL CAMPO ELECTRICO TIENE UN VALOR DISTINTO DE CERO, E IGUAL A CERO EN CASO CONTRARIO.
