Show affiliationsThe emission of light from within a sub-wavelength metal-clad cavity is investigated. We find that emitters placed inside such a cavity emit into the coupled surface plasmon–polariton mode supported by this structure. We use grating structures to couple the non-radiative coupled surface plasmon–polariton modes to light and present the results of measurements of photoluminescence from such structures in the form of dispersion curves. We discuss our findings in the context of sub-wavelength cavities as a means to control the emission of light.
