An experimental investigation of multisolitons using an erbium doped fiber amplifier and a fiber optic ring resonator

We have successfully generated the mutisoliton pulses using a Gaussian pulse in a fiber optic ring resonator incorporating an erbium-doped fiber (EDF) and a semiconductor optical amplifiers (SOAs). The multisoliton memory time within the system is also measured. Initially, the Gaussian input pulse is pumped and amplified through the EDF and the SOAs, respectively. The suitable experimental values, such as drive current, coupling power, and the fiber ring radius, are arranged to generate the multisoliton pulses. In application, the wider multisoliton band can be generated by adjusting the suitable system parameters. Results obtained have shown that the multisoliton with a free spectrum range and spectrum width of 2.4 and 0.96 nm is achieved. The memory time and the maximum soliton output of 15 min and of 5.94 dBm, respectively, are noted

Micro-current source generated by a WGM of light within a stacked silicon-graphene-au waveguide

A micro-current source using the drive electron mobility model is proposed by using the non-linear micro-ring resonator. The system consists of a nonlinear microring resonator known as Panda ring resonator made of InGaAsP/InP. The stacked waveguide (plasmonic island) of silicon-graphene-gold is formed at the center of the Panda ring, through which the whispering gallery mode (WGM) of light can be controlled and generated by the central ring it allows the driven electron mobility within the gold layer that can increase WGM beam acceleration and device current density with respect to the input optical power and ring parameters. The simulation results are obtained using the Opti-wave and MATLAB software programs. Results have shown that the relationship between the input of optical power and driven output current density can be obtained

Mode-locked self-pumping and squeezing photons model in a nonlinear micro-ring resonator

Photon squeezing and self-pumping within a nonlinear microring GaAsInP/P resonator are modeled and simulated, based on practical, published device parameters. A slowly varying amplitude pulse is input to the system, with a pulse width of 20 ns, a wavelength of 1.55 µm and peak power of 100 mW. The nonlinear effect resulting from the photons within the nonlinear ring resonator can be increased by adding external nonlinear coupling where, in this case, two nonlinear side rings are provided. The Dirac approach is used to generate the squeezed photons within the system. Three different device structures have been investigated, which include an add-drop filter, and a modified add-drop filter with two inner and outer side ring coupling resonators, where the nonlinear four-wave mixing effect is introduced. By using the commercial Opti-wave and MATLAB programs (in which suitable parameters have been chosen), the balance between the creation and annihilation operators can form the squeezed photons, which can be seen at the edge and center rings. The results obtained have shown that the squeezed center photon optical path (between 0 and 1 nm can be obtained) can be useful for interferometry, photon sources, and security code and sensor applications

Naked-eye 3D imaging model using the embedded micro-conjugate mirrors within the medical micro-needle device

A micro-conjugate mirror (MCC) is designed and modified using a nonlinear microring resonator system, a system consists of a nonlinear microring resonator known as a Panda ring resonator. 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
