In recent decades*, t*here has been a phenomenal growth in the field of photonic crystal research and has emerged as an interdisciplinary area. Photonic crystals are usually nanostructured electromagnetic media consisting of periodic variation of dielectric constant, which prohibit certain electromagnetic wave frequency ranges called photonic bandgaps to propagate through them. Photonic crystals elicited numerous interesting features by unprecedented control of light and their exploitation is a promising tool in nanophotonics and designing optical components. The book ‘Advances in Photonic Crystals and Devices’ is designed with 15 chapters with introductory as well as research and application based contents. It covers the following highlighted features:

• 
  

  Basics of photonic crystals and photonic crystal fibers

  
  

  Different theoretical as well as experimental approaches

  
  

  Current research advances from around the globe

  
  

  Nonlinear optics and super-continuum generation in photonic crystal fibers

  
  

  Magnetized cold plasma photonic crystals

  
  

  Liquid crystal defect embedded with graphene layers

  
  

  Biophysics and biomedical applications as optical sensors

  
  

  Two-dimensional photonic crystal demultiplexer

  
  

  Optical logic gates using photonic crystals

  
  

  A large number of references

  
  

The goal of this book is to draw the background in understanding, fabrication and characterization of photonic crystals using a variety of materials and their applications in design of several optical devices. Though the book is useful as a reference for the researchers working in the area of photonics, optical computing and fabrication of nanophotonic devices, it is intended for the beginners like students pursuing their masters’ degree in photonics.
