Abstract

We present the novel system of molecular distributed sensors using dark soliton pulse array, whereas the multi dark soliton sources can be generated and the molecular distributed sensors presented via an optical multiplexer (MUX). Initially, the dark soliton array with different center wavelengths can be generated, then the transmission molecules/atoms can be secured by using the dark soliton behaviors, whereas the dark soliton valley can be configured as the molecule/atom trapping potential well, which can be used to trap molecule/atom. In this case, the transported molecules/atoms in the router can be used to form the molecular distributed sensors, whereas the induced changes in the molecular distributed sensors can be formed and measured via the drop port of each output multiplexer.

Distributed photon network sensors via a wavelength router

Kreangsak Tamee, Somsak Mitatha, Preecha P. Yupapin

This study proposes a novel system of multi-photons generation and networking using an optical add/drop filter incorporating two nanoring resonators and the wavelength routers. By using some suitable parameters of the input and the control signals via an input and add ports, the intense optical fields can form and propagate within the system. Simulation results obtained have shown that multi-photons/atoms trapping pulses can be generated by using dark solitons and Gaussian pulses into the system, which can be used to form the multi-variable network for photons/atoms trapping and transportation via the wavelength routers. In application, the proposed system can be fabricated on a chip, in which the use for network sensors (communications) can be realised.

A Novel Multi Optical Tweezers Generation using a Dark Soliton for Transportation Atom/Molecule

Nithiroth Pornsuwancharoen, p Sanpoang

Abstract We propose a novel system of the optical tweezers array generation using dark soliton control within and add/drop filter control light by light. The dynamic tweezers are generated within an add/drop filter, where the number of tweezers within the add/drop filter can be tuned and amplified. The smallest tuned tweezers width are 0.02-0.05 nm are achieved, where the number of tweezers are 10-20 in an array. We have also theoretically shown that the dynamic tweezers can be controlled and tuned by varies the couple coefficient (k) between 0.1-0.9 and the radius of ring resonator between 10-20 |j.m, which is available for trapping and transportation in the communication up­link system via a add/drop filter. In application, the transmission of tweezers with different molecules and wavelengths can be performed within the transmission link, which is available for high density molecular transportation for wireless communication in near future.

Molecular Buffer

Preecha Yupapin

Optical buffer is recognized as an essential component in a wavelength router, in which packets of data can be stored for resolving packet contention problem and also to delay the outgoing packets [1-2]. In practice, optical router patents have been proposed and recorded [3-5], which can be useful for various applications. Recently, promising techniques of microscopic volume trapping and transportation within an add/drop multiplexer have been reported in both theory [6]and experiment [7], respectively. The transporter in these techniques is known as an optical tweezer. The technique for generating optical tweezers has become a powerful tool for manipulating of micrometer-sized particles. Useful static tweezers have now been well recognized and realized. The use of dynamic tweezers has also been realized in practical works [8-10]. Schulz et al. [11] have shown that trapped atoms between can be transported between two optical potentials. Optical tweezers use forces exerted by intensity gradients in strongly focused beams of light to trap and move nanoscopic volumes of matter. During the movement, another combination of forces is induced between photons due to their interactions caused by photon scattering effects. The field intensity can also be adjusted and tuned to the desired gradient field and scattering force so that the suitable trapping force can be formed. Thus, by configuring the appropriated force for the transmitter/ receiver part, nanoscopic particles can be transported over a long distance. In this chapter, the methods for generating the dynamic optical tweezers/vortices using a dark soliton, a bright soliton and a Gaussian pulse propagating within an add/drop optical multiplexer with two nanoring resonators (PANDA ring resonator) will be discussed. The dynamic behaviors of a soliton and Gaussian pulses are well described. [12]. By using the proposed system, the transceiver can be integrated to form a single device. The transceiver can be used to transport nanoscopic volumes of matter [13], especially, molecules in liquid core waveguide [14, 15], drugs, and DNA, where a buffer is needed before the substance reaches its destination.

Dynamic optical tweezers: Experiment

Somsak Mitatha, Suthichai Noppanakeepong, J. Ali +1 more

We have experimentally generated the optical tweezers in the form of a dark soliton pulse using the Stimulated Brillouin Scattering (SBS) system. This is the first time ever found on the use of the highly intense pulse in the form of a dark soliton to perform the dynamic light trapping probe known as a ¿dynamic optical tweezers¿. The advantage of the generated tweezers is that it can be used to transmit and transport the trapping atom/molecule into the optical device and communication network, which can be claimed as the dynamic optical tweezers transportation, for used in many frontier applications. The multi-optical tweezers generated, with high capacity regime can then be used for multi-optical tweezers transmission. The various applications to form the frontier research using photon, atom, molecule, DNA, electron and ion trapping for atomic tools, tiny synchrotron, molecular networks, bottom up atom/molecule assembly, ozone repair etc. are described. The experimental details and model of the optical tweezers generation and related characteristics are described. The interesting simulation results of a dark soliton generation for the optical tweezers are also analyzed and discussed in various applications.

NOVEL OPTICAL TRAPPING TOOL GENERATION AND STORAGE CONTROLLED BY LIGHT

Phichai Youplao, Thanawat Phattaraworamet, Somsak Mitatha +2 more

We propose a novel system of an optical trapping tool using a dark-bright soliton pulse-propagating within an add/drop optical filter. The multiplexing signals with different wavelengths of the dark soliton are controlled and amplified within the system. The dynamic behavior of dark bright soliton interaction is analyzed and described. The storage signal is controlled and tuned to be an optical probe which can be configured as the optical tweezer. The optical tweezer storage is embedded within the add/drop optical filter system. By using some suitable parameters, we found that the tweezers storage time of 1.2 ns is achieved. Therefore, the generated optical tweezers can be stored and amplified within the design system. In application, the optical tweezers can be stored and trapped light/atom, which can be transmitted and recovered by using the proposed system.
