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

Design Elliptic Lowpass Filter with Inductively Compensated Parallel-Coupled Lines

AbstractThis paper presents a simple technique to design an ellicptic transfer fuction microstrip lowpass filter based on a ection of doubly inductive compensated parallel-coupled lines. The proposed lowpass filter has the suppression performance to suppress the signal transmission in transition and stopband better than the filter based on the conventional coupled lines. The proposed design procedures are convenient with the closed form design equation. To emonstrate the techniques performance, simulated and measured results at 0.9GHz cut off frequency LPF with ncompensated and the compensated structures are compared. The measured results obtained from the proposed LPF exhibit 0.2dB insertions, less than 20dB return loss and more suppression performance than 35dB at 1.8GHz

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

The uses light source wavelength source was centered at 800 nm, where the conversion stability of 1600 fs is noted. The linearity trend of the conversion stability is confirmed

On-chip electro-optic multiplexing circuit using serial microring boxcar filters

© 2018 The Authors We propose a new variant of electro-optic multiplexing scheme using the boxcar filter arrangement. The circuits consist of multistage add-drop multiplexers that can offer external input-output connections. Input from a single light source can be fed into the system through the input port or through the free-space from light fidelity (LiFi) node. The light signal is fed into boxcar filters and the roll-off bands are obtained. The output of the circuits is formed at the drop, through and the whispering gallery mode (WGM) node of the circuit output. By using the electro-optic conversion in Si-Graphene-Au layer stack, time division (TDM), wavelength division (WDM), frequency division multiplexing (FDM) can be performed. The simulations have shown that a combination of 7 roll-off bands with the maximum spectral widths or bandwidths of ∼6.09 µm or ∼7.63 THz can be obtained

AbstractAn integrated scanned differential LDV has been proposed using planar lightwave circuit (PLC) technology. By using the proposed LDV, the measurement position can be scanned in depth direction without any mechanical movement. The PLC technology is utilized in the proposed design for achieving a compact optical circuit. The characteristics of the proposed LDV are simulated with a design model based on grating equations for AWGs. The simulation result reveals that the measurement position can be changed over the range of 46 mm in the depth direction without mechanical movement when the displacement between output sides of two waveguide arrays is 30 mm

High-density WGM Probes Generated by a ChG Ring Resonator for High-density 3D Imaging and Applications

In this paper, the ultra‐wideband source for light fidelity (LiFi) and high‐density 3D imaging applications is proposed. The system consists of an add‐drop multiplexer. The center ring is formed by the Chalcogenide glass (ChG), which is coupled with two GaAsInP/P side rings. The nonlinear effect within the side rings (phase modulators) is induced in the central ring. The superposition of light signals from side rings generates wider wavelength band, which makes the original input. The output is the set of squeezed light pulses known as whispering gallery mode (WGM) which is generated at the center of the system. Three different input sources are investigated, where the simulated results are comparatively plotted and discussed. The results show that the wavelength of 1.30 μm is the best input source. The output wavelengths band is ranged from 0.7‐3.1 μm, which is suitable for LiFi source and high‐density 3D imaging applications

Meditation mathematical formalism and Lorentz factor calculation based-on mindfulness foundation

Mindfulness foundation is an excellent method of the human spiritual development by the reasonable thinking and consideration, which was established by Lord Buddha a long time ago. There are four ways of thinking and consideration-(i) form (body), (ii) sensation, (iii) spiritual and (iv) Dhamma. In this paper, we propose the use of the form consideration for the spiritual development, in which the form can be considered thoroughly inside the body by the spiritual projection. By using the nonlinear microring resonator known as a Panda-ring resonator, the electromagnetic (EM) signals called polaritons can be generated by the coupling interaction between the intense EM fields and the ionic diploes within the almost closed system, where the dipoles can obtain from the coupling between the gold grating and the strong electromagnetic fields. In the manipulation, cells, tissues, and organs inside the human body can communicate with the spiritual (polaritonic) signals and investigation. The simulation results obtained have shown that the Lorentz factor of 0.99999959 is obtained. The successively filtering of the signal circulation within the body during the meditation can be formulated and the meditation behaviors modeled. The aura, the stopping, and the cold body states can be configured and explained
