Photonic crystals are the subject of intense study due to their capability to provide precise control of optical transmission characteristics through the choice of their periodic lattice parameters and the material with which they are fabricated. The sensitivity of photonic crystal band structure and defect transmission states to refractive index changes either at planar boundaries of a 2-D crystal or at individual lattice sites, make these structures potentially attractive for integrated point detection biosensor devices. 1-D Photonic crystal (PC) and 2-D PC based sensors were developed and studied in terms of sensitivity with different types materials functionalized on the surface. An extensive sensitivity analysis was done on both the devices to study the parameters that majorly effect device performance and the results from the proposed designs were found to be higher in comparison to published literature. Upon sucessfully designing of 1-D PC and 2-D PC sensors with high sensitivity these devices were fabricated to test them practically for various bio-materials. We demonstrated a 1-D PC sensor to detect pH change by coating thin film of hydrogel on PC surface which offers bio-compatibility for various bio-sensing applications. The 1-D PC sensor has optical sensitivities around 197nm/RIU in detecting refractive index change and 0.824nm per nanometer of thickness change of hydrogel on the surface of silicon gratings. We also developed a thin film coating procedure of hydrogel on 1-D PC sensor surface with high degree of uniformity. Thin film of hydrogels has many advantages over thick layer in terms of response time and enhancement in sensitivity. Silicon gratings were silanized so that the hydrogel is chemically bound to its surface and the micro-scale gratings devices were coated with a thin layer of 187.9nm of hydrogel using spin coating technique with high degree of uniformity. A fast response from thin layer of hydrogel integrating on optical sensor and high sensitivity makes these devices very attractive for bio-sensing applications. Selectivity is another important aspect in the design of a biosensor. Thus, much effort has been exercised for developing a wide-range immobilization techniques that can covalently or ionically anchor to the surface of silicon based PCs devices. We demonstrate a 1-D PC sensor based biosensor to detect functionalized protein binding on its surface. The 1-D PC sensor has a sensitivity of 1.61nm per a nanometer of thickness change of bio-material on the surface of silicon gratings. Functionalizing proteins on gratings surface by eliminating unspecific bindings makes this device highly selective and efficient. Streptavidin of concentration 0.016æmol/ml was functionalized on silicon substrate and biotin of 12æmol/ml was used as a target molecule in our experiments for detection. Normal transmission measurements of 1-D PC sensors were made in air at different stages of immobilization, bare silicon grating, after attaching streptavidin and after trapping biotin. Besides protein detection, detection of DNA hybridization is also important for low volume, high selectivity biosensors. We also demonstrated the detection of functionalized DNA on 1-PC sensor surface as well as detection of the hybridization process with its complimentary DNA. The silicon 1-D PC designed have sensitivities upto 2.43nm per a nanometer of thickness change in bio-materials of refractive index 1.542 on its surface and 70nm/RIU in detecting refractive index change of 6nm thick bio-material coating on its surface. Immobilization of DNA on chip silicon device surface and there by hybridizing with its complimentary strand makes this device more selective and efficient in detection. The order of concentration of DNA solution used in this experiment is in nano-molar range and was functionalized on silicon substrate using layer by layer technique. Normal transmission measurements of 1-D PC sensors were made in air at different stages of immobilization, bare silicon grating, after functionalizing chemical linkers, after immobilizing ssDNA-A and after hybridizing with its complimentary ssDNA-B. Hybridization experiments were done with non-complimentary ssDNA-C as well and no shift in transmission spectra was found which shows very good selectivity.

Deals not only with the properties of the radiation modes inside the crystals but also with their peculiar optical response to external fields. A general theory of linear and nonlinear optical response is presented in a clear and detailed fashion using the Green’s function method. Important recent developments such as the enhancement of stimulated emission, second harmonic generation, quadrature-phase squeezing, and low-threshold lasing are likewise treated in detail and made understandable. Numerical methods are also emphasised. This book provides both introductory knowledge for graduate and undergraduate students and important ideas for researchers.

This book illustrates original pathways to manipulate light at the nanoscale by means of surface electromagnetic waves (here, Bloch surface waves, BSWs) on planar dielectric multilayers, also known as one-dimensional photonic crystals. This approach is particularly valuable as it represents an effective alternative to the widely exploited surface plasmon paradigm. After a brief overview on the fundamentals of BSWs, several significant applications of BSW-sustaining structures are described. Particular consideration is given to the propagation, guiding, and diffraction of BSW-coupled radiation. Further, the interaction of organic emitters with BSWs on planar and corrugated multilayers is investigated, including fluorescence beaming in free space. To provide greater insight into sensing applications, an illustrative example of fluorescent microarray-based detection is presented. The book is intended for scientists and researchers working on photon management opportunities in fields such as biosensing, optical circuitry, and lighting.

The role of dielectric mirrors is very important in optics. These are used for several purposes like imaging, fabricating laser cavities, and so on. The basis for the propagation of photons in dielectric mediums is the same as electrons in solid crystals. If the electrons can be diffracted by a periodic potential well, photons could also be equally well diffracted by a periodic modulation of the refractive index of the medium. This idea led to the development of many new artificial photonic materials and optical micro- and nanostructures. Since the mechanism of light guidance is essentially due to the microstructural features of the medium, a wide variety of photonic structures, e.g., photonic band-gap fibers in 1D and photonic band-gap crystals in 2D and 3D, can be realized. Photonic Crystals - A Glimpse of the Current Research Trends essentially highlights the recent developments in the arena of photonic crystal research. It is expected to be useful for expert as well as novice researchers; the former group of readers would be abreast of recent research advancements, whereas the latter group would benefit from grasping knowledge delivered by expert scientists.

In recent decades, there 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.
