Abstract: In this paper, the use of molecular buffer and network for molecular diagnosis is presented. The trapping molecule is formed and transmitted into the required target via the molecular buffer and bus network. The optical trapping tool in the application of blood circulation manipulation analysis use the PANDA ring resonator system incorporating with bus network. The trapping force is formed by the combination of the gradient field and scattering photons. By using the blood circulation system, the blood pressure control, molecular diagnosis, and in situ surgery can be provided.

Abstract: We propose the use of molecular networks for drug delivery and diagnosis applications. Three modules of molecular networks such as bus, star,and ring networks are designed and manipulated based on a micro and nanoring resonator system. The transportation of the trapping molecule by light in the networks is described, the theoretical background is reviewed. However, the problems of large microscopic volumes and networks may be caused problems, in which the searching for new guide pipe and medium for instance, nanotube and specific medium and crosstalk effects will be the issue of investigations. Moreover, the qualities of network reliability are measurement in the form of signal transmission, i.e. signal to noise ratio (SNR) and crosstalk effects are discussed in details.

Abstract: We firstly propose the simple system of an attosecond light pulse generation by using a soliton pulse circulating in the integrated micro ring devices. The ultra short pulse in the atto scale regime and its beyond can be easily generated. Simulation results obtained have shown that the generation of a very narrow pulse and sharp tip is achieved. In principle, light pulse known as soliton pulse is input into a three stage micro ring resonators, where the ring radii are within the range from 5-15 microns. With some selected parameters such as ring radius, coupling ratio and nonlinear refractive index, the attosecond pulse is generated and achieved. The potential applications of using such a narrow pulse for new generation optical lithography, high density CD writing, high resolution interferometer, surface roughness and high speed optical computing, quantum computing are discussed.

Abstract: We propose a new design of the secured packet switching using the nonlinear behaviors of soliton in a micro ring resonator, where the nonlinear penalty of light traveling in the device becomes benefit. The chaotic signals are generated by a Kerr effects nonlinear type of soliton in a micro ring resonator, where the control input power can be used to specify the output filtering signals. Some device parameters are chosen and simulated using the proposed model. Results obtained have shown in good agreement with the practical device behaviors. The potential of using such a device for communication security is performed and discussed. For instance, the packet switching of the chaotic encoding data increases from the chaotic signal encoding of 100 bit/s. Results obtained have shown the potential of using such a proposed device for the tunable band-pass and band-stop filters, in which the packet switching data can be performed and secured.
