This book focuses on the development and set-up of fibre Bragg grating (FBG) and no-core fibre (NCF) sensors. It discusses the properties of the sensors and modelling of the resulting devices, which include electronic, optoelectronic, photovoltaic, and spintronic devices. In addition to providing detailed explanations of the properties of FBG and NCF sensors, it features a wealth of instructive illustrations and tables, helping to visualize the respective devices' functions.

This book introduces optical soliton control in micro- and nanoring resonator systems. It describes how the ring resonator systems can be optimized as optical tweezers for photodetection by controlling the input power, ring radii and coupling coefficients of the systems. Numerous arrangements and configurations of micro and nanoring resonator systems are explained. The analytical formulation and optical transfer function for each model and the interaction of the optical signals in the systems are discussed. This book shows that the models designed are able to control the dynamical behaviour of generated signals.

The behavior of light in small scale optics or nano/micro optical devices has shown promising results, which can be used for basic and applied research, especially in nanoelectronics. Small Scale Optics presents the use of optical nonlinear behaviors for spins, antennae, and whispering gallery modes within micro/nano devices and circuits, which can be used in many applications. This book proposes a new design for a small scale optical device-a microring resonator device. Most chapters are based on the proposed device, which uses a configuration know as a PANDA ring resonator. Analytical and numerical methods demonstrate that many applications can be exploited using this device, in particular when it is coated with metallic material. The book begins with the background and description of the PANDA ring resonator. The authors examine optical bistability in microring resonators and test the analytical results with those predicted by the OptiFDTD software package. They then describe their new design for a microring resonator device, which can be used to generate four forms of light on a chip, while also allowing the storing and harvesting of trapped atoms/molecules. The four behaviors of light, for instance, fast, slow, stopping, and storing, can be manipulated and seen simultaneously by using the PANDA ring planar waveguide, which can be fabricated and tested on-chip. Chapters examine optical spin, nano-antennas, optical mesh networks, micro-optical gyroscopes, and spin transport networks. They also address applications for optical devices, including molecular motors for drug discovery, short pulse lasers for treatment of cancer, microsurgery, nano-antenna use in radiotherapy, and neuron cell communications. There are many other possibilities of applications for the PANDA ring resonator, such as quantum coding, optical tweezers, and stopping light, which will play an important role in future optical devices.

Nanotechnology has been recognised as the interesting subject of research and investigation in either theory or experiment for a decade, where many research works and implementations have shown the significant growth and progress in many related technologies. Recently, the use of a small wave guide known as micro and/nanoring resonators has shown the potential of applications in many research areas, especially, in computer, communication and signal processing in the nanoscale regime. This book presents the immerging techniques that can be merged into one particular subject, which is known as Nano Communications Networks. In applications, such devices, techniques or systems can be integrated and used for some particular applications.

There are many nano-parts composted and integrated to be parts of a human body, which can be investigated and improved by using nanotechnology. Nano-medicine has become the important subject of the world of health and beauty today, in which much of the research in this field has become the challenge and basis for our future developments. In this book, the nano-device known as a PANDA ring resonator is designed and used to form the applications in medicine, especially, nano-medicine. By using the practical optical device and thin film technology, the designed devices and systems can form the human body embedded device, which can be used as the human body embedded devices. There are three major areas of research subjects: drug delivery, molecular diagnosis and therapy and artificial organs integrated to be a monograph book.

Non-linear behaviours of light have been recognised as the penalty in the subject of optical science and technology. However, the authors have shown the interesting results that the non-linear property of light pulse, especially, an optical soliton, can be probed into the specific device or system to be beneficial in various cases; for instance, a soliton pulse within a nano-waveguide can form many unexpected applications. Firstly, the basic property of a soliton is analysed and described. Secondly, the use of a soliton pulse within a non-linear waveguide that can perform the various cases of benefit and application is described. The principle and application details of the systems, such as soliton background soliton in communication, sensing applications, high resolution optical lithography and spectroscopy, quantum measurement and metrology, quantum information, and finally the promising results of dark-bright soliton behaviours and related applications are proposed. The potential of applications using the proposed device and techniques for nanoscale technology is discussed herein. This is a benefit to scientists, engineers and technologists for a wide range of application in the area of optical science and technology.
