Abstract

We propose a novel system of the dynamic potential well generation and control using light pulse control within an add/drop optical filter. The multiplexing signals of the dark solition with bright/Gaussian pulses are controlled, tuned and amplified within the system. The optical storage rings are embedded within the add/drop optical filter system, whereas the generated optical signals can be stored and amplified within the design system. In application, the storage signals can be configured to be an optical trapping tool which is known as optical tweezers, where the high field peak or well can be formed. The advantages are that the dynamic well can be stored and the array of well can be generated for multiple well applications. The difference in time of the first two dynamic wells of 1 ns is noted.

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.

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.

In Figures 4.4 (a)–(b), the tweezers in the form of potential wells are seen. It can be used for atom/ molecule trapping. The potential well depth (peak valley) can be controlled by adjusting the system parameters, for instance, the bright soliton input power at the add port and the coupling coefficients. The potential well of the tweezers is tuned to be the single well and seen at the drop port, as shown in Figure 4.4(c). In application, the optical tweezers in the design system can be tuned and amplified as shown in Figures 4.2 and 4.4. Therefore, the tunable optical tweezers can be controlled by the dark-bright soliton collision within the add/drop optical system by adjusting the parameters of the input power at the input and add ports, respectively. The output power at the throughput port is shown in Figure 4.2(c), where the single potential well with the optical power of 15 W is seen.
