Resumen
En este trabajo se desarrolló y validó experimentalmente un sensor dual de índice de refracción y de temperatura basado en un diseño interferométrico que integra fibra monomodo (SMF), fibra multimodo sin núcleo (NCF) y nuevamente fibra monomodo (SMF). La estructura SMS se utilizó como filtro y se incorporó en un láser en anillo de fibra dopada con erbio para mejorar la precisión de detección del sensor. Los resultados experimentales muestran que el sensor presenta una excelente respuesta lineal en la detección del índice de refracción, con una sensibilidad de 96.639 nm/RIU en un rango de medición de 1.346 a 1.406, además de una notable sensibilidad con la temperatura.
