    (2012) Farrah Dilla Zainol; Rangsan Jomtarak; Suzairi Daud; Chat Teeka; Jalil Ali; Preecha P. Yupapin; F.D. Zainol; Institute of Advanced Photonics Science, Nanotechnology Research Alliance, Universiti Teknologi Malaysia, Johor Bahru 81310, Malaysia; email: fairy-elie@yahoo.com
    In this paper, we propose a new design of the atom bottom-up technique that uses an optical trapping tool to form the atom trapping layer within a thin-film grating. By using a PANDA ring resonator, where atoms can be trapped, pumped, and controlled by light, the trapped atoms/molecules can be selected, filtered, and embedded within the required thin-film grating layers to manufacture nanobattery. In application, P-type or N-type atom can be prepared, trapped, and embedded within the desired thin-film layers, and finally, the microbattery can be manipulated. The theoretical background of light pulse in a PANDA ring resonator is also reviewed. © 2002-2012 IEEE.

    Filter design using multi-bragg reflectors
    (2012) Fairuz Diyana Ismail; Muhammad Safwan Aziz; Chat Teeka; Jalil Ali; Preecha Phromphan Yupapin; P.P. Yupapin; Nanoscale Science and Engineering Research Alliance, Faculty of Science, King Mongkut's Institute of Technology Ladkrabang, Bangkok 10520, Thailand; email: kypreech@kmitl.ac.th
    In this paper, we present the use of mathematical modeling of dielectric mirror known as known as Bragg reflector for optical design. A device system consists of the identical alternating layers using high and low refractive indices. Results obtained have shown that the model applications such as quarter-wavelength layers, unequal-length layers, short-pass and long-pass filters, and transmission filter design can be simulated and plotted.

    Nanocommunication networks
    (Nova Science Publishers, Inc., 2012) Preecha P. Yupapin; Somsak Mitatha; Jalil Ali; Chat Teeka
    Optical devices have become interesting tools that can be used in various applications. The use of such devices have been investigated in many areas such as E/O (electrical/optical) and O/E(optical/electrical) signal converters; optical signal processing; optical sensor; optical communication and medicine, etc. More interesting applications have been introduced such as the use of a micro/nano scale device, which has become both interesting and challenging. In this book, the behavior of light(light pulse) within the micro and nano scale device(ring resonator) is investigated. This can be integrated to form circuit and system devices that can be used for atom/molecule trapping and transportation; optical transistor; fast calculation device(optical gate); nanoscale communication and networks and a device for medical applications. © 2012 by Nova Science Publishers, Inc.

    Nanoscale nonlinear panda ring resonator
    (CRC Press, 2012) Preecha P. Yupapin; Chat Teeka; Muhammad Arif Jalil; Jalil Ali
    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. © 2012 by Taylor & Francis Group, LLC.
