Description |
The recently reported inward growing self-assembling method is used to fabricate photonic crystal heterostructures in less than 6 h using polymeric colloidal suspensions. Structural characterization shows good ordering of the two types of photonic crystals constituting the heterostructure. The reflection/transmission spectra measured from the (111) plane of the heterostructure clearly demonstrate the signature of the double photonic stop band. The reduction in the reflectance values obtained for the heterostructure is explained in terms of the interface roughness. The double photonic stop band of the heterostructures exactly matches the stop bands of the individual photonic crystals.(C) 2007
