Abstract

Surface plasmon polaritons (SPPs) are surface-bounded electromagnetic waves, propagating along a metal-dielectric interface. Due to larger wavenumber of SPPs compared with propagating light in free-space, additional couplers are required to excite SPPs. Dielectric prisms, gratings, apertures, and optical antennas are widely used. Recently, controlling excitation property of SPPs with coherent characteristics of incident lights, such as polarization and interference has been demonstrated. In this work, we propose a coherent plasmon cavity whose energy density can be tuned by polarization of the incident light. With polarization-sensitive aperture array, it is possible to launch counter-propagating SPPs with phase difference controlled by an angle of polarization. By rotating the polarization angle by 90 degrees, the energy density inside the cavity is enhanced 45 times larger compared with the minimum case.
