Controllable FWM within a PANDA Ring

AbstractIn this paper, we present the controllable four-wave mixing (FWM) within PANDA ring resonator based-on optical soliton manipulation. After a dark soliton pulse is fed into an input port of the resonator, the FWM can be formed within the system and detected simultaneously at the output ports. Under the resonant condition, the FWM can be controlled by adding Gaussian or bright soliton at the add port. Whenever a soliton(photon) is absorbed by an object, an angular momentum of either + ħ or –ħ is imparted to the object, in which two possible soliton states known as soliton spins are seen. In application, the controllable FWM can be used atom/photon manipulation

A new concept of multi electron-hole pair generation using dark-bright soliton conversion control

In this paper, we have derived and presented a new concept of multi electron-hole pair generation by using dark-bright soliton collision within the modified add/drop filter, which it is known as PANDA ring resonator. By using the dark-bright soliton conversion control, the obtained outputs of the dynamic states can be used to form the multi electron-hole pair, which can be available for communication security application

All-optical switches based on GaAs/AlGaAs quantum dots vertical cavity

In this paper, an all-optical switch based on self-assembled GaAs/AlAs quantum dots (QDs) within a vertical cavity is designed and proposed. Two essential aspects of this novel device have been investigated, which include the QD/cavity nonlinearity with appropriately designed mirrors and the intersubband carrier dynamics inside QDs. The vertical-reflection-type switches have been investigated with an asymmetric cavity that consists of 12 periods of GaAs/Al0.8Ga0.2As and 25 periods for the front and back mirrors, respectively. The thicknesses of the GaAs and AlGaAs layers are chosen to be 89 and 102 nm, respectively. To give a dot-in-a-well (DWELL) structure, the 65 nm dimension of Si was recommended to deposit within a 20 nm AlAs QW. Results obtained have shown that all-optical switching via the QD excited states has been achieved with a time constant down to 275-fs and over 29.5 nm tunable wavelengths. These results demonstrated that QDs within a vertical cavity have great potential to realize low-power, consumption polarization-insensitive and micrometer-sized switching devices for future optical communication and signal processing systems

All-Optical Nanoscale Microring Device and System Design for Nano Communication

AbstractIn this paper, we have shown that the two components (TE and TM waves) of polarized light are manipulated by using the orthogonal soliton pair within a PANDA ring resonator known as a dark-bright soliton pair. In operation, the orthogonal soliton sets can be generated by using the system. The optical field is fed into the ring resonator system, which is controlled by an optical switch by using a single microring. To form the initial spin states, the magnetic field is induced by an aluminum plate (Al) coupled on AlGaAs waveguides for optoelectronic spin-up and - down states. The optoelectronic spin is formed by using the TE and TM wave components. In this manipulation, the electromagnetic radiation is formed by using the orthogonal soliton pulses. In fact, they are photons, which behave like elementary particles. Hence, the spin axis of photon is always parallel to its direction of motion. Many orthogonal sets are also available and existed, in which the spin conservation of many particles is maintained for large scale system use. Therefore, for future applications, the use for high performance storage, low power magnetic logic, quantum logic, quantum gate, nano antenna, nano radio, and applications of spintronic sensing can be realized based on realistic device parameters

Atom bottom-up manipulation controlled by light for nanobattery use

We propose a new design of the atom bottom-up technique that uses an optical trapping tool to form the atom trapping layer within a thin film grating. By using a PANDA ring resonator, where atoms can be trapped, pumped and controlled by light, where finally, the trapped atoms/molecules can be selected, filtered, and embedded within the required thin film grating layers, which later can form the nanobattery. In application, P-type or N-type atom can be prepared, trapped and embedded within the desired thin film layers, where finally, the nanobattery can be manipulated. The theoretical background of light pulse in a PANDA ring resonator is also reviewed

Optical spin manipulation using dark-bright soliton behaviors in a panda ring resonator

A new concept of an optoelectronic spin generation using bright and dark soliton conversion behaviors within a modified optical add‐drop filters known as a PANDA ring resonator is proposed. The orthogonal solitons can be formed randomly within the system and detected simultaneously at the output ports. Under the resonant condition, the random transverse electric and magnetic fields of the solitons corresponding to the left‐hand and right‐hand photons can be generated. Whenever a photon is absorbed by an object, an angular momentum of either + ħ or –ħ is imparted to the object, in which two possible spin states known as optoelectronic spins are exhibited. Furthermore, the array of optoelectronic spins, i.e., many particles can be generated and controlled by using the proposed system, which can be used to form large scale spintronics applications
