  • Abstract
    A multitapered fiber-optic surface plasmon resonance (SPR) sensor for refractive index sensing has been fabricated and characterized. The sensor has been analyzed for different taper periods in a given sensing length. The sensing probe with the smallest taper period is found to be the most sensitive. In addition, the sensor is less fragile than previously studied tapered fiber-optic SPR sensors, as the core waist is not very thin in the present probe.
