Highly Sensitive Fiber Optic Refractive Index Sensor Using Multicore Coupled Structures

Abstract

In this paper, we demonstrate highly sensitive refractive index (RI) sensing based on multicore coupled structures. Specifically, we use a seven-core fiber (SCF) as the sensing element. The interaction of the SCF and its surroundings is induced by controllably etching material from the cladding in order to expose its external cores. Thus, the sensor… (More)
