Synthesis of Poly(ST-co-COPSI)particles by soap-free emulsion copolymerization and its optical properties as photonic crystals

, , , ,
Highly charged, submicron-sized polymeric colloidal particles can self assemble into 3-dimentional(3D) opal structure which is useful template for photonic crystal. In this report, optical properties of poly[Styrene(ST)-co-Allyloxy-2-hydroxypropane sulfonic acid sodium salt(COPSI)] polymeric microspheres with number [...]

Design and implementation of silicon-based optical nanostructures for integrated photonic circuit applications using Deep Reactive Ion Etching (DRIE) technique

, , , , , , ,
Photonic crystals (PhC) are artificially engineered periodic structures capable of manipulating and shaping optical signals. Nanoscale photonic crystals is expected to add new functionalities to the next generation of optical integrated circuits by providing novel [...]

Surface Enhanced Raman Scattering by 2D Photonic Crystals: Enhancement and Reproducibility

, , , , , , , , , , , ,
Surface Enhanced Raman Scattering (SERS) is a widely utilised technique to enhance the weak Raman spectrum of molecules, enabling detection and identification of ultralow concentrations of particular species. We show both experimentally and theoretically how [...]
