Electron-beam lithography was used to create a two-dimensional wavelength-scale periodic texture on one of the cavity mirrors with nanometer precision. In the microcavity, Bragg scattering is expected to provide a full continuous optical band gap and flat dispersion of optical waveguide modes in the visible regime. When the luminescing material is placed inside the 2D patterned microcavity, the coupling of the luminescing matter to the photonic eigenmodes of the metallic microcavity is observed. We found that planar microcavity transmission result is in good agreement with the theoretical calculation. For the laterally structured metallic microcavity samples, we found that the dispersion of optical modes inside the microcavity is significantly altered compared with the planar metallic microcavity.
