Abstract

We report a parametric study of a long-range plasmon waveguide for the modal profiles, effective index and propagation losses as a function of the metal layer thickness and the variations in the refraction index of the upper cladding. Such device can be used as an optical biosensor. All calculations are performed using COMSOL Multiphysics, and the amplitude- and phase- responses of the device are obtained from the changes in the real and imaginary part of the effective index of the plasmon mode, respectively.
