This book investigates the behavior of light (light pulse) within the micro- and nano-scale device (ring resonator), which can be integrated to form the device, circuits, and systems that can be used for atom/molecule trapping and transportation, optical transistor, fast calculation devices (optical gate), nanoscale communication and networks, and energy storage, etc. The large demand of small-scale device, especially, with light signal processing is needed. This book discusses device (nano device) design and simulation, which can be useful for practice in the near future.

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.

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.

This book focuses on areas of integrated optics which is an emerging technology. This book includes the basic concept of a micro ring resonator and its characteristics. The generalised approach of the device design is described, and some cases of applications are provided. The non-linear aspect of the micro ring resonator is also analysed; there are some cases of applications provided. Evolving technologies in communications, quantum communication, non-linear communication, ultra-fast switching and soliton switching, quantum chaotic and solitons are discussed.

Microring/nanoring resonator is an interesting device that has been widely studied and investigated by researchers from a variety of specializations. This book begins with the basic background of linear and nonlinear ring resonators. A novel design of nano device known as a PANDA ring resonator is proposed. The use of the device in the form of a PANDA in applications such as nanoelectronics, measurement, communication, sensors, optical and quantum computing, drug delivery, hybrid transistor and a new concept of electron-hole pair is discussed in detail.
