Preface

The book is oriented on topics concerning innovative materials, photonic crystal waveguides and lasers including plasmonics, technological aspects and geometrical layouts. Photonic crystal waveguides are considered one of the main applications of two-dimensional (2-D) photonic crystals. They have received significant attention, both experimentally and theoretically. In particular, 2-D photonic crystal lasers, potentially have great practical applications in the mid-IR region due to their unique features in, for example, surface emission, circular beams, low threshold operation, miniaturization and simplicity of on-chip monolithic integration, etc. Furthermore, innovative materials and plasmonic photonic crystals have recently been the focus of intense study for different applications. The goal of this book is to provide an overview about different implementations of photonic crystals.

This book is structured into three main sections:
