Abstract
Focused ion beam (FIB) lithography was used to inscribe a periodic array of nanoholes directly on gold-coated optical fiber end-faces. The excitation of the surface plasmon polaritons of the nanohole arrays on the optical fiber end-faces provided the basis of a refractive index sensor for liquids. This optical fiber based surface plasmon resonance sensor is compact and has the potential to be used in biomedical applications. A sensitivity of approximately 294 nm per refractive index unit (RIU) has been demonstrated for this sensor.
