Dual resonance mechanisms facilitating enhanced optical transmission in coaxial waveguide arrays

Orbons, S. M.; Haftel, M. I.; Schlockermann, C.; Freeman, D.; Milicevic, M.; Davis, T. J.; Luther-Davies, B.; Jamieson, D. N.; Roberts, A.


We experimentally and computationally demonstrate high transmission through arrays of coaxial apertures with different geometries and arrangements in silver films. By studying both periodic and random arrangements of apertures, we were able to isolate transmission enhancement phenomena owing to surface plasmon effects from those owing to the excitation of cylindrical surface plasmons within the apertures themselves.
