Abstract

UN DISPOSITIVO DE MODULACION OPTICA INCLUYE PRIMERAS (1, 4, 6) Y SEGUNDAS (2, 5, 7) PLACAS PARALELAS OPTICAMENTE TRANSMISIVAS, QUE TIENEN UN MATERIAL DE CRISTAL LIQUIDO FERROELECTRICO INTERCALADO ENTRE ELLAS. UNA PLURALIDAD DE MIEMBROS SEPARADORES (10), CADA UNO SUJETO A UNA DE LAS PLACAS, SE SITUAN ENTRE LAS PLACAS PARA MANTENER EL ESPACIAMIENTO DE LAS PLACAS. LOS MIEMBROS ESPACIADORES FORMAN PAREDES QUE DEFINEN CANALES (11) PARALELOS, QUE CONTIENEN MATERIAL DE CRISTAL LIQUIDO, CUYOS CANALES SE EXTIENDEN PARALELOS A LAS PLACAS. ESTOS CANALES SE COMUNICAN A LO LARGO DE SUS LONGITUDES CON CAVIDADES (12), AL MENOS PARCIALMENTE DEFINIDAS POR LOS MIEMBROS (10) ESPACIADORES. ESTAS CAVIDADES PUEDEN ORIGINARSE SEGMENTANDO CADA PARED, CONSTITUYENDO LAS SEPARACIONES ENTRE SEGMENTOS SUCESIVOS LAS RESPECTIVAS CAVIDADES. ALTERNATIVAMENTE, CADA PARED (14) PUEDE TENER UNA PARED (10) AUXILIAR PARALELA DE MENOR ALTURA, CERCA A ELLA, PERO ESPACIADA DE ELLA, FORMANDO EL ESPACIO ENTRE LAS DOS PAREDES UNA CAVIDAD.
