Abstract
A Kretschmann-type surface plasmon resonance waveguide sensor is analyzed using the wide-angle
beam-propagation method (BPM) with the complex Padé approximant and the finite-difference time-domain (FDTD)
methods based on the recursive convolution (RC) and piecewise linear RC (PLRC) techniques. The wavelength responses
of the sensor are calculated, and a detailed comparison of the numerical results is made. The BPM results are
validated through a comparison with the FDTD results, in which the PLRC technique is required in terms of accuracy.
The waveguide sensor shows a maximum absorption wavelength shift from 0.609 to 0.623 <i>µ</i>m, as the refractive index of an analyte is increased from 1.330 to 1.334, which is
comparable to the sensitivity of the conventional Kretschmann configuration.
