Abstract

SE PRESENTA UN INTERFEROMETRO DE "SAGNAC" (19) QUE ESTA DEFINIDO POR UN ACOPLADOR DE FIBRA OPTICA 50:50 PARA CUATRO PUERTOS (20), DOS PUERTOS DE SALIDA (38, 40) QUE ESTAN ACOPLADOS JUNTOS MEDIANTE UN AMPLIFICADOR DE LASER SEMICONDUCTOR NO LINEAL (3) EN SERIE ENTRE UN PAR DE FIBRAS OPTICAS (22, 24). LAS PERDIDAS DE ACOPLAMIENTO ENTRE LOS PUERTOS (38, 40) Y EL AMPLIFICADOR (30) SON DIFERENTES. UN IMPULSO DE ENTRADA ACOPLADO AL PUERTO (34) DEL ACOPLADOR (20) SE DIVIDE EN DOS PARTES QUE SE PROPAGAN DE FORMA CONTRARIA DESDE UNO DE LOS PUERTOS DE SALIDA (38) HASTA EL OTRO. LAS PARTES VUELVEN AL ACOPLADOR (20) CON UNA INTENSIDAD DEPENDIENTE DEL DESPLAZAMIENTO RELATIVO DE FASE. ESTO DA COMO RESULTADO QUE LA CONMUTACION DE UN IMPULSO DE ENTRADA EN EL PUERTO DE ENTRADA (34) ENTRE LOS PUERTOS DE ENTRADA (34 Y 36) DEPENDA DE LA INTENSIDAD DEL IMPULSO DE ENTRADA. EL DISPOSITIVO PUEDE SUMINISTRAR UNA CONMUTACION DEPENDIENTE DE LA INTENSIDAD EN NIVELES DE POTENCIA OPTICA MENORES A 250(MU)W.
