title: Multi-channel SPR biosensor based on PCF for multi-analyte sensing applications.
abstract: This paper presents a theoretical investigation of a novel holey fiber (Photonic Crystal Fiber (PCF)) multi-channel biosensor based on surface plasmon resonance (SPR). The large gold coated micro fluidic channels and elliptical air hole design of our proposed biosensor aided by a high refractive index over layer in two channels enables operation in two modes; multi analyte sensing and self-referencing mode. Loss spectra, dispersion and detection capability of our proposed biosensor for the two fundamental modes (HE(11)(x) and HE(11)(y)) have been elucidated using a Finite Element Method (FEM) and Perfectly Matching Layers (PML).
