Microstructured polymer optical fiber-based surface plasmon resonance sensor

Abstract

We propose a surface plasmon resonance sensor based on microstructured polymer optical fiber (mPOF) made of polymethyl methacrylate (PMMA) with the cladding having only one layer of air holes near the edge of the fiber. In such sensor, the nanoscale silver metal film can be deposited on the outer side of the fiber, which is easily realized. Numerical simulation results show that spectral and intensity sensitivity are in the range of 8.3×10^-5~9.4×10^-5RIU.
