Abstract
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.
