Nanophotonics

Optical device is become the interesting tool which can be involved in various applications. The use of such device has been investigated in many areas, for instance, E/O (electrical/optical) and O/E(optical/electrical) signal converters, optical signal processing, optical sensor, optical communication and medicine, etc. has been realized. More interesting applications have been appeared, especially, when the device dimension is reached the micro/nano scale regime, in which many aspects of investigation become the challenge. In this book, we investigate 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 device(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 is a device(nano device) design and simulation which can be useful for practical in near future.
