Abstract

LOS AISLADORES OPTICOS SUPRIMEN EL REFLEJO DE VUELTA DE LA LUZ. SEGUN LA INVENCION SE EMITE UNA LUZ PROVINIENTE DE UN PRIMER CONDUCTOR DE LA ONDA DE LUZ (2) SOBRE UN SUBSTRATO (1) BAJO EL ANGULO AGUDO EN EL CAMPO OPTICO DE UNA AGUJA DE CAMBIO HACIA UN SEGUNDO CONDUCTOR DE LA ONDA DE LUZ (3). EL PRIMERO EL SEGUNDO CONDUCTOR DE LUZ NO SE TOCAN ENTRE SI. EN EL SEGUNDO CONDUCTOR HAY UNA PLAQUITA DE LONGITUD DE LA ONDA DEL CUARTO (7). LA LUZ EN EL PRIMER CONDUCTOR DE LA ONDA DE LUZ (2), ESTA POLARIZADO DE FORMA LINEAL Y ELECTRICA EN UN PLANO COPLANAR QUE VA HACIA LA SUPERFICIE DEL SUSTRATO (1). YA QUE LA LUZ DE ESTA DIRECCION POLARIZADA ES BASTANTE MENOR AL PASAR ENTRE LOS CONDUCTORES DE LA ONDA DE LUZ (2, 3), SE SUPRIME LA LUZ POLARIZADA Y ELECTRICA QUE VA DE FORMA VERTICAL HACIA LA SUPERFICIE , ASI COMO LA LUZ QUE ES UN REFLEJO DE VUELTA DEL PASO DE LA PLAQUITA LONGITUDINAL DE LA ONDA DEL CUARTO (7), QUE PRECISAMENTE TIENE LA DIRECCION DE ESTA POLARIZACION Y QUE SE SUPRIME CASI COMPLETAMENTE EN EL PRIMER CONDUCTOR DE LA ONDA DE LUZ (2). ESTE AISLADOR OPTICO SE UTILIZA TAMBIEN EN LOS INTERFEROMETROS.
