Abstract
UN CONMUTADOR OPTICO NO LINEAL QUE INCLUYE UN MEDIO DE GANANCIA OPTICA SEMICONDUCTOR. EL CONMUTADOR ESTA DISPUESTO PARA CONECTAR UNA SEÑAL DE UNA PRIMERA LONGITUD DE ONDA EN RESPUESTA A UNA SEÑAL DE CONTROL DE UNA SEGUNDA LONGITUD DE ONDA APLICADA AL MEDIO DE GANANCIA OPTICA. EL INDICE DE REFRACCION DEL MEDIO DE GANANCIA SE MODIFICA EN RESPUESTA A LA SEÑAL DE CONTROL. UNA SEÑAL DE MANTENIMIENTO OPTICO DE UNA TERCERA LONGITUD DE ONDA SE APLICA AL MEDIO DE GANANCIA. LA SEÑAL DE MANTENIMIENTO OPTICO BOMBEA EL MEDIO DE INTERCAMBIO OPTICO Y DE ESTE MODO FIJA EL NIVEL FERMI. EL CONMUTADOR PUEDE INCORPORARSE A DEMULTIPLIXADORES OTDM, CIRCUITOS DE RECUPERACION DE RELOJERIA, CONVERTIDORES DE LONGITUD DE ONDA Y OTROS MECANISMOS.
