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.

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.

Resonator System

A new technique of optical tweezer generation and rotation within a modified add-drop optical filter is presented. A proposed system is made up of silica and InGaAsP / InP consisting of linear optical add-drop filter incorporating two nonlinear nanorings on both sides of the micro ring. This particular configuration is known as a "PANDA" ring resonator. Light pulse, for instance, Gaussian, bright and dark solitons are fed into the system through different ports such as drop port and through port. By using the practical device parameters, the simulation results are obtained using the Optiwave and MATLAB programs. Results are obtained by both analytical and numerical methods, which found that the orthogonal solitons can be generated using the proposed system. The tweezer rotation is formed by the spin-up and spin-down states for the input signals, created by using transverse electric and magnetic field within the PANDA ring resonator system. The output signals can be controlled by system parameters such as ring radii, coupling constants, input signals and applied to various applications for tweezer spins such as trapping, transportation and rotation, which can be useful for molecular motor applications.

Quantum Signal Processing

A molecular cryptography technique using optical tweezers, is proposed. The optical tweezer transports the molecules in the communication 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.

AbstractThe fabrication of three-dimensional (3D) microscale structures is critical for many applications, including strong and lightweight material development, medical device fabrication, microrobotics, and photonic applications. While 3D microfabrication has seen progress over the past decades, complex multicomponent integration with small or hierarchical feature sizes is still a challenge. In this study, an optical positioning and linking (OPAL) platform based on optical tweezers is used to precisely fabricate 3D microstructures from two types of micron-scale building blocks linked by biochemical interactions. A computer-controlled interface with rapid on-the-fly automated recalibration routines maintains accuracy even after placing many building blocks. OPAL achieves a 60-nm positional accuracy by optimizing the molecular functionalization and laser power. A two-component structure consisting of 448 1-µm building blocks is assembled, representing the largest number of building blocks used to date in 3D optical tweezer microassembly. Although optical tweezers have previously been used for microfabrication, those results were generally restricted to single-material structures composed of a relatively small number of larger-sized building blocks, with little discussion of critical process parameters. It is anticipated that OPAL will enable the assembly, augmentation, and repair of microstructures composed of specialty micro/nanomaterial building blocks to be used in new photonic, microfluidic, and biomedical devices.

AbstractWe construct the Lax pair and Darboux transformation for the three-component coupled Hirota equations including higher-order effects such as third-order dispersion, self-steepening, and stimulated Raman scattering. A special vector solution of the Lax pair with 4×4 matrices for the three-component Hirota system is elaborately generated, based on this vector solution, various types of mixed higher-order localised waves are derived through the generalised Darboux transformation. Instead of considering various arrangements of the three potential functions q1, q2, and q3, here, the same combination is considered as the same type solution. The first- and second-order localised waves are mainly discussed in six mixed types: (1) the hybrid solutions degenerate to the rational ones and three components are all rogue waves; (2) two components are hybrid solutions between rogue wave (RW) and breather (RW+breather), and one component is interactional solution between RW and dark soliton (RW+dark soliton); (3) two components are RW+dark soliton, and one component is RW+bright soliton; (4) two components are RW+breather, and one component is RW+bright soliton; (5) two components are RW+dark soliton, and one component is RW+bright soliton; (6) three components are all RW+breather. Moreover, these nonlinear localised waves merge with each other by increasing the absolute values of two free parameters α, β. These results further uncover some striking dynamic structures in the multicomponent coupled system.
