NOVEL OPTICAL TRAPPING TOOL GENERATION AND STORAGE CONTROLLED BY LIGHT

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.

Multifunction interferometry using the electron mobility visibility and mean free path relationship

A conventional Michelson interferometer is modified and used to form the various types of interferometers. The basic system consists of a conventional Michelson interferometer with silicon‐graphene‐gold embedded between layers on the ports. When light from the monochromatic source is input into the system via the input port (silicon waveguide), the change in optical path difference (OPD) of light traveling in the stacked layers introduces the change in the optical phase, which affects to the electron mean free path within the gold layer, induces the change in the overall electron mobility can be seen by the interferometer output visibility. Further plasmonic waves are introduced on the graphene thin film and the electron mobility occurred within the gold layer, in which the light‐electron energy conversion in terms of the electron mobility can be observed, the gold layer length is 100 nm. The measurement resolution in terms of the OPD of ∼ 50 nm is achieved. In applications, the outputs of the drop port device of the modified Michelson interferometer can be arranged by the different detectors, where the polarized light outputs, the photon outputs, the electron spin outputs can be obtained by the interference fringe visibility, mobility visibility and the spin up‐down splitting output energies. The modified Michelson interferometer theory and the detection schemes are given in details.

Microring stereo sensor model using Kerr–Vernier effect for bio-cell sensor and communication

In this paper, a micro-stereo sensor is proposed using two-identical Panda-ring resonators, which are coupled by jointed drop ports. When light from the identical coherent sources is fed into the system via the input ports, the coupling outputs are obtained at the drop port at the resonant condition. These are mixed signals in the form of stereo signals. By using different input power between the right and left systems, the phase difference generated by the Kerr-Effect in the non-linear medium leads to the shift in the coupling outputs. The shift in the center wavelength is the primary measurement of interest along with coupling crosstalk signals that are also visible at the output. The measurement self-calibration of the two channels is confirmed by the mixed channel signals. In the manipulation, the crosstalk signals can be used to interpret the cross-communication of bio-cells. The crosstalk results have shown the optical crosstalks of ∼2.0 and ∼2.5 dB are calculated and obtained, respectively. The stereo sensor sensitivity of ∼5.70 nmW−1is noted.
