Abstract

UN DEFLECTOR DE RAYO DE LUZ ELECTRO-OPTICO PLANAR DISPONE DE UNA HILERA DE PRISMAS DE DEFLEXION ADYACENTES CON ELECTRODOS A LOS CUALES PUEDE SER APLICADA UNA TENSION ELECTRICA. LA INVENCION CONSISTE ESENCIALMENTE EN EL HECHO DE QUE EL RAYO DE LUZ ES GUIADO A UN CRISTAL DE NIOBATO DE LITIO DE CORTE DE GRADO CERO O TANTALATO DE LITIO, CON PREFERENCIA EN UNA GUIA DE ONDA LAMINADA MONOMODAL QUE SE EXTIENDE A LO LARGO DE LA MISMA SUPERFICIE, Y DE MODO QUE LOS PRISMAS DE DEFLEXION CONSISTEN CADA UNO DE ELLO EN DOS AREAS TRIANGULARES O PRISMATICAS EN DONDE SE GENERA UN SENTIDO DE POLARIZACION SUSTANCIALMENTE UNIFORME EN ZONAS CON SENTIDOS OPUESTOS ESPONTANEAMENTE DE POLARIZACION MEDIANTE INVERSION DEL SENTIDO DE POLARIZACION DETERMINADO POR MEDIO DEL VECTOR DE CAMPO ELECTRICO. LAS ZONAS TRIANGULARES ADYACENTES DISPONEN DE SENTIDOS OPUESTOS DE POLARIZACION. UN ELECTRODO RECTANGULAR QUE CUBRE LAS AREAS TRIANGULARES SE APLICA SOBRE LA SUPERFICIE SUPERIOR DEL CRISTAL Y SE APLICA UN CONTRAELECTRODO ENLA SUPERFICIE INFERIOR DEL CRISTAL. COMO CONSECUENCIA DE ESTAS MEDIDAS, SE INDUCE UN CAMBIO EN EL INDICE DE REFRACCION CON SIGNOS OPUESTOS EN LAS ZONAS TRIANGULARES ADYACENTES O PRISMATICAS CUANDO SE APLICA UN VOLTAJE ENTRE EL ELECTRODO Y EL CONTRAELECTRODO. LA DISTRIBUCION DE INDICE DE REFRACCION ES EN SU MAYORIA UNA DISTRIBUCION IDEAL EN DIENTE DE SIERRA. SE DESCRIBE TAMBIEN UN PROCESO PARA LA ELABORACION DE UN DEFLECTOR DE RAYO DE LUZ DE ESTE TIPO.
