A novel design of an optical trapping tool for tangle protein (tau tangles, β-amyloid plaques) and molecular motor storage and delivery using a PANDA ring resonator is proposed. The optical vortices can be generated and controlled to form the trapping tools in the same way as the optical tweezers. In theory, the trapping force is formed by the combination(More)
A new optical trapping design to transport gold nanoparticles using a PANDA ring resonator system is proposed. Intense optical fields in the form of dark solitons controlled by Gaussian pulses are used to trap and transport nanoscopic volumes of matter to the desired destination via an optical waveguide. Theoretically, the gradient and scattering forces are(More)
In this study, we have generated terahertz (THz) frequency by a novel design of microring resonators for medical applications. The dense wavelength-division multiplexing can be generated and obtained by using a Gaussian pulse propagating within a modified PANDA ring resonator and an add/drop filter system. Our results show that the THz frequency region can(More)
The directional fiber couplers consist of multi fibers joint have been successfully fabricated by heating of torch flame at atmospheric pressure and pulling the fiber coupling region mechanically at micro scale. Good performance of the coupling coefficient and the coupling ratio was obtained by setting the initial parameter of coupler machine such as the(More)
We have proposed and optimize the optical parameters to fabricate multiport fiber coupler to support microactuator device based on fusion and elongation techniques. The coupling coefficient between the fibers was derived by using Hankel and Bessel function. However, the fusion technique was experimentally described as a function of elongation speed. Good(More)
