Abstract
UN INTERRUPTOR OPTICO QUE SELECTIVAMENTE TRANSMITE O NO TRANSMITE LUZ DE UN FIBRA OPTICA DE ENTRADA (10) A UNA GUIA DE ONDAS OPTICA DE SALIDA (11,12) TIENE COMO UNA DE LAS GUIAS DE ONDA DE ENTRADA (10) Y SALIDA (11,12) UNA FIBRA OPTICA QUE ES FLEXIBLE Y ESTA MONTADA PARA SER CAPAZ DE MOVERSE HACIA LA OTRA Y DE ALEJARSE DE ELLA, Y UN ELECTRODO (14) DISPUESTO PARA SOMETER LA GUIA DE ONDAS OPTICA A UN CAMPO ELECTROSTATICO. EN USO, LA APLICACION DE UN POTENCIAL ELECTRICO AL ELECTRODO (14) CAUSA QUE LA GUIA DE ONDAS OPTICA SE MUEVA EN UNA DIRECCION PARA PERMITIR O EVITAR EL ACOPLAMIENTO OPTICO ENTRE LAS GUIAS DE ONDA Y DE AQUI LA OPERACION COMO INTERRUPTOR. LA FIBRA OPTICA ES UNA FIBRA TIPO D DE MODO QUE ES MAS FLEXIBLE EN ESA DIRECCION Y ESTA PROVISTA ESTA FIBRA CON UN GRADO DE AUTOALINEAMIENTO. SE PREFIERE QUE LA GUIA DE ONDAS OPTICA SEA ELECTRICAMENTE NO CONDUCTORA Y QUE EL INTERRUPTOR OPTICO INCLUYA MAS DE UN ELECTRODO (14) PARA PROPORCIONAR UN CAMPO ELECTROSTATICO NO UNIFORME. EN ESTE CASOLA GUIA DE ONDAS OPTICA SE MUEVE HACIA LA REGION DE MAS ALTA DENSIDAD DE CAMPO ELECTROSTATICO Y ASI SE MUEVE HACIA LA OTRA GUIA DE ONDAS O SE ALEJA DE ELLA PARA PERMITIR O EVITAR EL ACOPLAMIENTO OPTICO ENTRE ELLAS.
