Abstract

We present theoretical analysis of a fiber optic surface plasmon resonance (SPR) sensor utilizing a Bragg grating using the rigorous 3-D numerical modeling and the approximation of the equivalent planar (2-D) waveguide. It is demonstrated that the 2-D approach provides a good estimate of sensitivity of the sensor; however, it fails to describe the complex behavior of the spectral transmission.
