High Capacity Mobile Ad Hoc Network Using THz Frequency Enhancement

International Journal of Communications, Network and System Sciences 2010年第12期3卷 954-961页

作者： Sawatsakorn Chaiyasoonthorn phongphun Limpaibool Somsak Mitatha preecha p. yupapin 不详

We propose a new design of the high channel capacity in Mobile Ad Hoc Network that uses the dense wave-length division multiplexing wavelength enhancement, in which the increasing in channel capacity and sig-nal security can be provided. The increasing in number of channel can be obtained by the increasing in wavelength density, while the security is introduced by the specific wavelength filter, which is operated by the Ad Hoc node operator and link with other nodes in coverage by dedicated one-to-one in direct or relay node. The optical communication wavelength enhancement is reviewed. The advantage is that the proposed system can be implemented and used incorporating with the existed communication link in both infrastruc-ture-based and Ad Hoc networks wireless network, where the privacy can be provided, which is discussed in details.

Rabi oscillation generation in the microring resonator system with double-series ring resonators

Optoelectronics Letters 2015年第5期11卷 342-347页

In this paper, a microring resonator(MRR) system using double-series ring resonators is proposed to generate and investigate the Rabi oscillations. The system is made up of silicon-on-insulator and attached to bus waveguide which is used as propagation and oscillation medium. The scattering matrix method is employed to determine the output signal intensity which acts as the input source between two-level Rabi oscillation states, where the increase of Rabi oscillation frequency with time is obtained at the resonant state. The population probability of the excited state is higher and unstable at the optical resonant state due to the nonlinear spontaneous emission process. The enhanced spontaneous emission can be managed by the atom(photon) excitation, which can be useful for atomic related sensors and single-photon source applications.

Sustainable Tourism Using Security Cameras with privacy protecting Ability

引用

Journal of Information Security 2010年第2期1卷 68-73页

作者： V. prashyanusorn Y. Fujii S. Kaviya S. Mitatha p. p. yupapin 不详

For sustainable tourism, a novel method of security camera operation is proposed. In the method, security cameras, which encrypt the taken images and store them into the memory card inside, are used. Only when crimes occur, the memory cards are taken out from the cameras and the images are decrypted with the key and viewed by the city government and/or the police. When no crimes occur, images are overwritten by the new ones after a week automatically without being viewed by anyone. By using the stand-alone cameras without wiring to the control center, the installation cost and the operation cost are much lower than CCTV cameras. By using image encryption, the privacy of the tourists is protected. Using this system, high density installation of the security cameras with very low cost can be realized in encryption with image encryption privacy protection

New Communication Bands Generated by Using a Soliton pulse within a Resonator System

引用

Circuits and Systems 2010年第2期1卷 71-75页

作者： p. p. yupapin M. A. Jalil I. S. Amiri I. Naim J. Ali 不详

We propose a novel system of a broadband source generation using a common soliton pulse (i.e. with center wavelength at 1.55 ?m) propagating within a nonlinear microring and nanoring resonators system. A system consists of a micro ring resonator system incorporating an add/drop filter, whereas the large bandwidth signals can be generated, stored and regenerated within the system. By using the appropriate parameters relating to the practical device such as micro ring radii, coupling coefficients, linear and nonlinear refractive index, we found that the obtained multi soliton pulses have shown the potential of application for dense wavelength division application, whereas the different center wavelengths of the soliton bands can be obtained via the add/drop filter, which can be used to increase the channel capacity in communication network.
