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

A novel optical radio on fiber multi-channel by micro ring resonator system

AbstractWe propose a novel system that can be used to generate the new optical radio on fiber communication continuous variable channel using a Gaussian pulse propagating within a nonlinear micro-nanoring resonator system. By using the wide range of the Gaussian input for instance, when the input pulses of the common lasers with centre wavelengths from 1,300nm are used, which this system is simple for used. Results obtained have shown that more available wavelength bands and frequency domain(THz) from the different ring parameter and wavelengths can be generated, which can be used to form new optical to high frequency ranges, whereas the use of the very high channel capacity for personal wavelength and very high security and multi-channel in network applications is plausible

By using the monochromatic input light source, the electro-optic signals can be generated and functioned as the step up and down conversion by mean of the on-chip optoelectronic transformer. The step up and down of the electro-optic related power conversions can be obtained via the input and drop port connections. The results obtained have shown that the flexible up and down electro-optic conversion ratios of 1: 5 and 10:1 for the step up and down conversions, respectively.

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

The design of the microsensor system for biosensors using the plasmonic island is proposed. The sensor head is formed by the stacked layers of silicon-graphene-gold materials. The dual-mode operations of the sensor can be performed using the relationship of the changes between the electron mobility and optical phase, where the exciting environment can be light intensity (phase), electrical transient, heat, pressure, flavour and smoke, The change in light phase (intensity) in silicon and conductivity (mobility) in gold layers cause change in the output measurands. The design and simulation interpretation of the sensor is presented. The sensor manipulation using the MCM arrangement is simulated and interpreted for biosensor applications 3D imaging can also be applied to the MCM function, where the 3D in situ sensor function is possible.

Plasmonic Op-Amp Circuit Model using the Inline Successive Microring Pumping Technique

The electro-optic power pumping system model using the inline successive technique within the modified add-drop filter is proposed. A pumping system consists of a closed loop panda ring resonator, from which the optical power is coupled inline into the system. By controlling the two side phase modulators, the whispering gallery mode (WGM) is generated by the amplitude-squeezed light within the modified add-drop filter. By using the proposed circuits, the low current can be applied into the system via a gold layer connection, from which the amplified output current can be obtained at the throughput port, which can be functioned as the electronic operational amplifier (Op-amp). In application, the WGM output is the amplified signal that can be used for the up (down) link in free space communication network called light fidelity (LiFi). The electro-optic signals conversion can be performed by the stacked layers of silicon-graphene-gold materials. The results obtained have shown that large gain is obtained at the WGM output, which is ~5×10-6cm².(V.sW)-1, when the pumping saturation time is ~2 fs. It concludes the suitability of our proposed model for light fidelity, LiFi up-down link conversion

Novel Kerr-Vernier effects within the on-chip Si-ChG microring circuits

We propose a new concept of the nonlinear effect called the Kerr-Vernier effect by using cascaded Si-ChG microring circuits. The circuit is simulated for two materials of different refractive indices which results in phase difference in propagating light and hence observed in the output signal. By varying the input power into the system, the Vernier effects in terms of the Kerr-Vernier effects are seen. In application, the comparative results of the two-channel outputs are used to form the phase sensors, while the self-calibration between the two-channel outputs can be performed. The change in wavelength at the whispering gallery mode of 8 nm is achieved when the applied input power was fixed at 10 mW. A sensitivity of ∼120 µm W-1is obtained for this proposed sensor

On-chip polariton generation using an embedded nanograting microring circuit

We have proposed a model of polariton generation, which is normally generated by the dipole and the strong coupling field interaction. This system consists of a gold grating embedded on the plasmonic island, which is embedded at the center of the nonlinear microring resonator, which is known as a panda-ring resonator. The strong coupling between the plasmonic waves and the grating can be formed by the whispering gallery mode (WGM) of light within a Panda-ring resonator, in which the output is a dipole-like particle known as a polariton and seen at the system output. By varying the energy of high-intensity laser pulse in the system and gold granting a strong field is generated at the output. A dipole is formed by a pair of the grating signals, where one propagates in the opposite direction of the other. By using suitable parameters, dipole-like signals can be generated. Theoretical formulation is performed for a two-level system and polariton oscillation frequency i.e., the Rabi frequency is plotted. The obtained ground and excited state frequencies of this two-level system are 187.86 and 198.20 THz, respectively

Nano-capacitor-like model using light trapping in plasmonic island embedded microring system

We have proposed the convincing electro-optic circuit for long life-time electron mobility emission. Light a monochromatic source is utilized as input into the circuit via the input port and trapped within the plasmonic island. It is a formed-like capacitor structure formed by the silicon-graphene-gold materials which are stacked layers. All circuit port ends have added the TiO2to form the reflectors. By selecting the suitable parameters, the fraction of the output power emission can be controlled at the add port, from which it can be successively pumping and trapped(stored) within the plasmonic island. The system energy saturation can be released by squeezing light behavior, therefore, the system is always balanced due to the successive pumping process. The results obtained of the single cell(circuit) have shown that the charging time and discharging times of the nano-capacitor-like of ∼2 to 3 s and 1000 h are achieved. This can be applied to long life mobility emission(discharge) of the capacity-like device. The mobility storage time within the island is 14,000 h, with the electron mobility of ∼3.0 × 10−7cm2Vs−1 is obtained

Characteristics of an on-chip polariton successively filtered circuit

Polaritonic signal processing model and manipulation using a microring successive filtering circuit are proposed. The polariton signals are generated by the coherent light within the microring embedded a gold nanograting island, from which the successive filtering of the polariton signals within the designed on-chip circuit is manipulated by adjusting the device end reflection coefficients. The almost closed system of the two-level system of polaritons is formed, where there are initially two oscillation frequencies called the Rabi frequencies, the ground an excited state respectively. The required signals of this characteristics study are presented in the domains of wavelength, time and frequency, which can be used to characterise the brain signals in the meditation situation. When the successive polariton switching time (Δt) is approaching zero, from which the stopping polariton state is established, while the polariton frequencies can be tunable. The results obtained have shown that switching time of the 2nd successive round-trip of 25.55 fs is obtained, and in addition, the tunable frequencies of the ground and excited states of the two-level system are achieved
