Multitweezers generation control within a nanoring resonator system

Abstract

We propose a novel system of 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 an optical tweezer, where the high field peak or well can be formed. The advantages are that the dynamic well can be stored and the array of wells can be generated for multiple wells applications. The different in time of the first two dynamic wells of 1 ns is noted.

Optical vortices generated by a PANDA ring resonator for drug trapping and delivery applications

“…The large gradient force is formed by the large depth of the laser beam, in which the stable trapping requires that the gradient force in the $-\widehat{z}$ direction, which is against the direction of incident light (dark soliton valley), and it is greater than the scattering force. By increasing the NA, when the focal spot size is decreased, the gradient strength is increased [23], which can be formed within the tiny system, for instance, nanoscale device (nanoring resonator).…”

Molecular filter on-chip design for drug targeting use

“…A novel designed PANDA microring resonator was proposed by the authors (Tasakorn et al 2010a). A PANDA ring is a modified optical add/drop filter that can be applied to many applications by changing the structure of PANDA and signals, in which the major behaviors are the two nonlinear side rings.…”

“…In the proposed design, the optical waveguide can be used to trap molecules/atoms (Suwanpayak et al 2011b, Youplao et al 2010, Tasakorn et al 2010b) with molecular filter constructed incorporating with the optical tweezer assembly, in which the trapped molecules can transfer to the device via the optical waveguide as shown in Figure 2. In simulation, the input signal is a bright soliton and Gaussian pulses at the peak power of 100 mW.…”

Drug trapping and delivery for Alzheimer's diagnosis

“…In this paper, the dynamic optical tweezers/vortices are generated using the optical pulses propagating within anadd/drop optical multiplexer incorporating two nanoring resonators (PANDA ring resonator) (Tasakorn et al 2010). By using the proposed system, the tangle protein and molecular motor can be trapped and transported/received into the optical waveguide by optical tweezers.…”
