Abstract
The complete polarimetric responses of oblique- and square- lattices of metal subwavelength hole arrays that display extraordinary optical transmission were examined. The Mueller scattering matrices were measured at normal and oblique incidence for plane wave illumination using a polarimeter employing four photoelastic modulators. The oblique array has strong natural optical activity combined with asymmetric (non-reciprocal) transmission of circularly polarized light. At oblique incidence the square lattice also shows asymmetric transmission at non-normal incidence, whenever the plane of incidence does not coincide with a mirror line. Symmetry considerations associated with non-reciprocal transmission are emphasized in a comparison with the complete polarimetric response of dissymmetric gold gammadion arrays.
