In this thesis photonic crystals are implemented as planar photonic crystals, i.e., optically thin semiconductor films with periodic arrays of holes etched into them, with a hole-to-hole spacing of the order of the wavelength of light in the dielectric media.

Photonic crystals (PhCs) are inhomogeneous dielectric media with periodic variation of the refractive index. In general, photonic crystals have a photonic band gap. That is the range of frequencies in which light cannot propagate through the structure. 1.2 History of photonic crystals.Abstract Biological photonic crystal (PC) patterns provide unique functionalities for the survival of creatures, such as the static identified patterns of butterfly wings, the mating function of the eye pattern of peacock feathers and the dynamic warning effect of the changing colour of a chameleon upon external stimulus.In recent decades, photonic crystals (PCs) have shown great potential in developing rewritable papers. However, existing PC papers still confront many challenges, including poor storage stability, short-cycle lifetime, monotonous colors, and absence of copying capability.

Photonic very fibre (PCF) refers to a different group of optical fibre that is dependant on the options of photonic crystals. The 3 kinds of photonic very fibre include hole fibre, photonic-bandgap fibre and Bragg fibre.Read More
Photonic devices such as 1D PhC nanocavities are one of the interesting structures to be used as optical sensors due to their capability to integrate with CMOS technology. We present in this study, a simple optical technique of detection based on 1D PhC nanocavities that gives good sensitivity for various types of chemicals.Read More
A photonic crystal is a periodic structure that modulates the refractive index at the scale of the wavelength of light. 449 This periodic structure is designed to form so-called â€śphotonic bandgapsâ€ť (i.e., a range of wave vectors for which light cannot propagate). To provide the full bandgap in all directions, a photonic crystal should be structured in three dimensions, which represents a.Read More
Abstract This thesis describes my research into the highly tuned naturally occurring 3D photonic structures that are present on a selection of insects. The experimental and theoretical work presented in this thesis was performed in both the optical and microwave regimes. The work performed in the optical regime included both the geometric.Read More
Photonic Crystals (PCs) are periodically structured dielectric materials with period in the range of the photon wavelength. Line- defects in photonic crystals can guide light due to the photonic band gap effect, different to the conventional total internal reflection.Read More
Abstract This dissertation discusses cholesteric liquid crystals (CLCs) and polymers based photonic devices including one-dimensional (1D) photonic crystal lasers and broadband circular polarizers. CLCs showing unique self-organized chiral structures have been widely used in bistable displays, flexible displays, and reflectors.Read More
In the beginning of the thesis there is a short introduction in the theory of photonic crystals, their fabrication and some of the various applications. The discussions of the main findings in the presented work are in the final three chapters.Read More
