What is Photonic polymer replicas from DBR PSi about?

Well-defined one-dimensional photonic polystyrene replicas showing a reflectivity at 654 nm have been successfully obtained by the removal of distributed Bragg reflector (DBR) porous silicon (PSi) template from the polystyrene composite film. XRD measurement indicates that the oxidized DBR PSi has been completely removed from the composite films. Optical reflectivity spectra were measured using a tungsten-halogen lamp and an Ocean Optics S2000 CCD spectrometer. Polymer replicas exhibit a sharp resonance in the reflectivity spectrum. The photonic band gaps of DBR-structured polymer replicas are narrower than that of polymer replicas from rugate PSi master. Optical characteristics of photonic polymer replicas indicate that the surface of polymer film has a negative structure of DBR PSi. These replicas are stable in aqueous solutions for several days without any degradation. The methods have been provided for the construction of photonic structures with polymers.
