Metallic　photonic　crystals　(MPCs)　with　different　periods　have　been　fabricated　by　solution-processed　method.　Scanning　electron　microscopy　images　show　that　the　structures　with　their　period　larger　than　400　nm　can　easily　maintain　their　morphologies　during　the　high　temperature　lift-off　process.　The　optical　properties　of　the　waveguided　MPCs　with　different　periods　have　been　investigated.　With　an　increase　in　the　period,　high-order　coupling　between　particle　plasmon　resonance　and　the　waveguide　resonance　modes　can　be　observed　in　the　spectra.　We　found　that　the　+/-　2　orders　coupling　of　the　structure　with　its　period　of　880　nm　has　similar　tuning　properties　to　the　+/-　1st　orders　coupling　of　the　430　nm　period　structures,　which　infers　us　that　we　can　use　the　structures　with　larger　period　that　can　be　controllably　fabricated　to　replace　the　ones　with　smaller　period.　The　results　we　obtained　in　this　work　provide　reference　for　further　applications　of　the　MPCs.　(C)　2013　Society　of　Photo-Optical　Instrumentation　Engineers　(SPIE)　[DOI:　10.1117/1.OE.52.3.034601]
