We　demonstrate　the　fabrication　of　two-dimensional　(2D)　metallic　photonic　crystals　(MPCs)　based　on　colloidal　gold　nanoparticles,　where　laser　interference　ablation　combining　subsequent　high　temperature　annealing　is　employed　for　the　construction　of　2D　gold　nano-dot　arrays　in　square　lattices.　The　microscopic　and　spectroscopic　properties　of　the　2-D　MPCs　are　systematically　characterized　by　the　scanning　electron　microscope　and　the　angle-resolved　optical　extinction　spectroscopic　measurements,　the　strong　coupling　between　the　waveguide　resonance　mode　and　the　particle　plasmon　resonance　of　the　MPCs　imply　the　success　of　the　fabrication　method,　which　show　potential　applications　in　optoelectronic　devices　and　sensors.
