Abstract

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.

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.

A New Design Optical Tweezers by Triple Ring Resonator

Metha Tasakorn, Nithiroth Pornsuwancharoen, Preecha P. Yupapin +1 more

We propose a new system of the multi-quantum tweezers array generation using a soliton generation control within the triple ring resonator system, whereas the dynamic tweezers can be generated within a microring device. By using the quantum processor, the entangle photon states of the tweezers can be formed, which is allowed to form the molecular quantum transmission. We have also theoretically shown that the optical tweezers can be controlled and tuned by varying the couple coefficient (κ) between 0.25 and 0.9, with ring resonator radii between 7 and 15 μm, which is available for molecule trapping. In application, the transmission of tweezers with different molecules or DNA can be performed, which is available for high density and security molecular transportation via the optical communication system.

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.

The optical tweezer generated by the dark soliton is in the form of a potential well. The dark soliton propagates inside nonlinear microring resonator (NMRR). Transportation of molecules is implemented when the dark soliton is used as input pulse. The input bright soliton control the output signal at the drop port of the system. Output optical tweezers can be connected to the quantum signal processing system consisting of transmitter and the receiver. The transmitter is used to generate the high capacity quantum codes within the series of MRR’s and an add/drop filter. The receiver will detect the encoded signals known as quantum bits. The transmitter will generate the entangled photon pair which propagates via an optical communication link. Here the smallest optical tweezer with respect to the full width at half maximum FWHM is 17.6 nm in the form of potential well is obtained and transmitted through quantum signal processor via an optical link.

The dynamic behavior of bright soliton interaction is analyzed and described. The signal is controlled and tuned to be an optical probe which can be configured as the multi optical tweezers. By using some suitable parameters, we found that the tweezers widths in add/drop at the drop ports are about 18 nm is achieved. Therefore, the generated multi optical tweezers can be amplified within the design system. In application, the optical tweezers train can be trapped light/atom, which can be transmitted and recovered by using the proposed system.
