Novel Evolving Concepts and Breakthroughs in Characterisation of Photonic Band-gap Materials - A Comprehensive Review

Photonic crystals (PhCs) also known as Photonic band-gap materials have been found very suitable and attractive optical materials for controlling and manipulating the flow of light. This paper gives a comprehensive overview and technical Methodology of Computation of Photonic Band Structure. Soliton compression has been briefly discussed. Fabrication and Characterization of Photonic Crystals in Photopolymer SZ2080 by Two-Photon Polymerization have been described. The case of dispersion engineered slow-light silicon photonic crystal waveguide has been theoretically discussed. Technology of controlling the emission of single excitons in Photonic Crystal Cavities has been briefly explained. A qualitative review of some important studies on the subject, especially in the research area has also been provided. Most importantly, some important recent breakthroughs in this field have been presented and technically discussed. It is expected that the paper should be really useful for the researchers and designers working in this evolving field.
