Micro-optical probe model using integrated triple microring resonators for vertical depth identification

The nonlinear microring resonator system is designed and the triple vertically Panda rings arranged for 3D imaging probe generation. The required whispering gallery modes (WGM) probe can be generated by controlling the input soliton and the reflected power within the microring system. It can be configured to be a microring conjugate mirror (MCR) and theoretically confirmed by the obtained nonlinear four-wave mixing output. The different depths of the MCCs are arranged by the differences of the vertical heights, which can offer the triple vertical probe requirement. The analytical solution of the WGM probe output is derived and the selected simulation results investigated. The results obtained have shown that the triple WGM probes can be generated and used for the 3D imaging detection, from which the two surface depths are ~ 2 and 4 µm are plotted, the calculated and the different colored shades seen. In application, such a proposed system may be used for the 3D imaging of the soft tissues (cells) investigations.

An MCC can be formed by adjusting the reflected light power from the Throughput and Add ports, from which the outputs can be detected by the Drop port output and 3D image construction can be performed. The short distance naked-eye 3D imaging transmission is accomplished, which can be confirmed by the four-wave mixing outputs, which is useful for 3D image transmission, bio-sensors and medical imaging and diagnostic applications.

Micropropulsion generation model and simulation by WGM acceleration within a Panda ring resonator system

ABSTRACTA microbeam accelerator is modeled and simulated using the analogy of whispering gallery mode (WGM) generated by light within a nonlinear microring resonator system, which is called a Panda ring structure and made by an InGaAsP/InP material. The WGM mode is generated after the suitable ring parameters and optical input introducing into the system, especially, the suitable two nonlinear side ring radii are employed. From which, the required multiple propulsion (acceleration) of WGM beams is achieved using the multiple vertical Panda ring layout (several layers). The accelerated WGM beams of the multiple ring circuits can be obtained by the coincident of the multiple Panda rings. The simulation result shows that the proposed ring resonator system can be potentially fabricated within the microscale range and used for a microthruster, in which the required driven force can be used to drive the spacecraft or satellite to the target destination, which is known as a thrust propellant. For example, the result of the propulsion of 2.619–66.81 μN can be obtained by a single device system, which means that the larger volume or area can be used to produce more propulsion output. For further application, the suitable input source such as the infrared light source can also be used to for the micro‐heat source, in which the large area of the device array may be useful for large area micro‐heat source usage. © 2016 Wiley Periodicals, Inc.

A system of microring resonators (MRRs) connected to an optical modified add/drop filter system known as a Panda ring resonator is presented. The optical soliton pulse of 60 GHz frequency band can be generated and used for Wireless Personal Area Network (WPAN) applications such as IEEE 802.15.3c. The system uses chaotic signals generated by a Gaussian laser pulse propagating within a nonlinear MRRs system. The chaotic signals can be generated via a series of microring resonators, where the filtering process is performed via the Panda ring resonator system wherein ultrashort single and multiple optical soliton pulses of 60 GHz are generated and seen at the through and drop ports, respectively. The IEEE 802.15.3c standard operates at the 60 GHz frequency band, and it is applicable for a short distance optical communication such as indoor systems, where the higher transmission data rate can be performed using a high frequency band of the output optical soliton pulses. The single and multi-soliton pulses could be generated and converted to logic codes, where the bandwidths of these pulses are 5 and 20 MHz, respectively. Thus, these types of signals can be used in optical indoor systems and transmission link using appropriate components such as transmitter, fiber optics, amplifier, and receiver.

SUMMARYA system consisting of a series of microring resonators, incorporating an add/drop system, is presented in order to create ultra‐short spatial and temporal single and multisoliton pulses, which can be used for indoor and outdoor optical communications. Chaotic noise can be generated by a bright soliton pulse propagating inside a nonlinear microring resonator system. The results obtained show that a single temporal and spatial soliton pulse, with full width at half maximums of 75 fs, 80 fs, 700 fs, 4.4 ps, and 0.30 nm, can be generated. The add/drop system can be used to generate a high number of ultra‐short soliton pulses in the ranges of nanometer/second and picometer/second. The simulated multisolitons have full width at half maximums of 16 ps, 20 pm, 130 ps, and 35 pm and free spectrum ranges of 500 ps, 0.57 nm, 3.5 ns, and 1.4 nm, respectively. The multisolitons generated at the drop port can be used in indoor optical communications, where the ultra‐short pulses with a variety of central wavelengths (from λ = 1550 to λ = 1560) from the through port can be multiplexed‐demultiplexed along an optical fiber with a length of 50 km. The filtered signals can be obtained at the end of the transmission link used for optical outdoor communications. Copyright © 2013 John Wiley & Sons, Ltd.

Generation Of Quantum Codes Using Up And Down Link Optical Solition

In this study, a system of continuous variable quantum code via a wavelength router is presented. The optical Kerr type nonlinearity in the nonlinear microring resonator (NMRR) induces the chaotic behavior. In this proposed system chaotic signals are generated by an optical soliton or Gaussian pulse within a NMRR system. Large bandwidth signals of optical soliton are generated by the input pulse propagating within the MRRs, which is allowed to form the continuous wavelength or frequency with large tunable channel capacity. Therefore, distinguished up and down links of wavelength or frequency pulses can be generated by using localized spatial soliton via a quantum router and networks. These selected up and down links pulses are more suitable to generate high secured quantum codes because of the greater free spectral range (FSR). The continuous quantum codes can be generated by using the polarization control unit and beam splitter, incorporating into the MRRs. In this work, frequency band of 10.7 MHz and 16 MHz and wavelengths of 206.9 nm, 1.448 μm, 2.169 μm and 2.489 μm can be obtained for QKD by using input optical soliton and Gaussian beam.

New WDM bands using a Gaussian pulse within a nano-waveguide

The new optical communication bandwidths (wavelength bands) using a Gaussian pulse propagating within a nonlinear microring resonator system is proposed. The Gaussian input pulses, for instance, when the input pulses of the common lasers with center wavelengths from 400 to 1500 nm are used, the required output wavelength bands can be obtained by controlling the coupling coefficients of the add/drop filter. Results obtained have shown that more available wavelength bands from the different center wavelengths can be generated, which can be used to form new dense wavelength division multiplexing bands.

Gaussian soliton generation using a 1.3 μm optical pulse in a micro-ring resonator for a new DWDM enhancement

We present a novel system of a Gaussian soliton generation using a 1.30 μm optical pulse in a nonlinear micro-ring resonator system, which can be used to form the soliton pulse trains within the new wavelength band. By using the suitable parameters, the soliton pulse trains with the center wavelength at 1.30 μm can be generated after the intense Gaussian pulse is input into the nonlinear micro-ring resonator system. The initial pulse bandwidth is enlarged and the signal amplified by the nonlinear Kerr effects type within the ring resonator. The simulation values are used associating with the practical device parameters, whereas the obtained results have shown that the wavelength enhancement of the center wavelength can be achieved. Furthermore, the maximum soliton output power of 12 W is obtained, which is available to perform the long-distance communication link. The common problem of soliton dispersion is minimized by the zero dispersion condition in this case. The major advantage of the proposed system is that the dense wavelength division of the center wavelength with the spectral width of 7.0 pm (10 −15 m) and the free spectrum range of 400 pm can be generated and achieved. This is available for the used/installed wavelength enhancement, which can provide more available channel capacity in the existed public optical network.

We propose a remarkably simple system of a continuous variable quantum key distribution using chaotic signals generated by a soliton pulse within a nonlinear micro-ring resonator system. By using the appropriate soliton input power and micro-ring parameters, continuous signals are generated spreading over the spectrum. Polarized photons are formed incorporating the polarization control unit into the micro-ring system, which allows different time slot entangled photons to be randomly formed. Two different frequency bands for up–down-link converters can be selected (filtered) and performed, which is available for the simultaneous up–down-link application in the telephone networks. Results obtained have shown that the application of such a system for continuous variable quantum cryptography via optical-wireless up–down-link converters within a single system is plausible.
