Ultrafast all-optical ALU operation using a soliton control within the cascaded InGaAsP/InP microring circuits

A dark-bright soliton conversion is used to perform the two arithmetic logic unit operations namely adder and subtractor operations. The advantage of the system such as power stability, non-dispersion and the dark-bright soliton phase conversion control can be obtained. The input source into the circuit is the bright soliton pulse, with the pulse width of 35 ps, the peak power at 1.55 µm is 1 mW. By using the dark-bright soliton conversion pair, the generated logic bits can be controlled, and the secure bits can be achieved. The simulation results show the output signal with a minimum loss of only 0.1% with respect to a low input power of 1 mW, and ultra-fast response time of about 1 ps can be achieved. It gives the ultra-high bandwidth of more than 40 Gbits−1. The circuit composes six microring resonators made of InGaAsP/InP material with smaller ring radii of 1.5 µm, and the total physical scale of the circuit less than 100 µm2.

Optical Spins and Nano-Antenna Array for Magnetic Therapy

Magnetic therapy is an alternative medicine practice involving the use of magnetic fields subjected to certain parts of the body and stimulates healing from a range of health problems. In this paper, an embedded nano-antenna system using the optical spins generated from a particular configuration of microrings (PANDA) is proposed. The orthogonal solitons pairs corresponding to the left-hand and right-hand optical solitons (photons) produced from dark-bright soliton conversion can be simultaneously detected within the system at the output ports. Two possible spin states which are assigned as angular momentum of either +ħ or -ħ will be absorbed by an object whenever this set of orthogonal solitons is imparted to the object. Magnetic moments could indeed arise from the intrinsic property of spins. By controlling some important parameters of the system such as soliton input power, coupling coefficients and sizes of rings, output signals from microring resonator system can be tuned and optimized to be used as magnetic therapy array.

Novel soliton cryptography using optical key generated by orthogonal dark-bright soliton pair

A new method of optical cryptography using dark-bright soliton conversion control within a modified add/drop optical filter is proposed. A pair of optical keys is randomly generated and transmitted into the transmission line, where finally the corrected keys between Alice (sender) and Bob (receiver) can be retrieved. In principle, the coincidence (orthogonal) dark-bright soliton pair has shown promising behaviors, especially when they propagate into the π/2 phase shifter, i.e. beamsplitter, the shift in phase of π/2 between dark and bright solitons is occurred and separated. Such behaviors can be used to form the orthogonal light modes (solitons), which are useful for cryptographic application, where in this case the long-distance cryptography can be easily managed. We have derived and presented a new concept of multi-orthogonal solitons generated by using dark-bright soliton pulses within the modified add/drop optical filter, which is known as a PANDA ring resonator. By using the dark-bright soliton conversion control, the obtained output of the dynamic states can be used to randomly form the multi-orthogonal soliton pairs, which can be available for computer and communication security applications, especially for long-distance link.

A Study of Dynamic Optical Tweezers Generation for Communication Networks

We propose a novel system of the dynamic optical tweezers generated by a dark soliton in the fiber optic loop. A dark soliton known as an optical tweezer is amplified and tuned within the microring resonator (MRR) system. The required tunable tweezers with different widths and powers can be controlled. The analysis of dark-bright soliton conversion using a dark soliton pulse propagating within a MRR is analyzed. The control dark soliton is input into the system via the add port of the add/drop filter. The dynamic behavior of the dark-bright soliton conversion is observed. The required stable signal is obtained via a drop and throughput ports of the add/drop filter with some suitable parameters. In application, generation of optical tweezers and transportation can be realized by using the proposed system, where the communication network is performed.

Novel communication security scheme using dark-bright soliton conversion behaviors

We propose a novel scheme of communication security using dark-bright soliton conversion behaviors in which the transmission signals can be secured by using the random codes generated by dark-bright soliton conversion within the system. The system consists of two parts, where first, an optical Mach Zhender interferometer (MZI) is used to generate the coincidence dark and bright soliton pair by using the (π/2) phase retarder (i.e., a coupler), in which |D〉 and |B〉 states represent the orthogonal dark and bright soliton pulses. The signals from through (Th) port are formed and transmitted via the transmission line to the end user. Second, the add/drop filter is used to separate(filter) the required signal form the transmission link, in which the Th and drop port signals are formed as a reference and signal, respectively. In this case, we assume that both solitons are input into the MZI ports simultaneously (coincidently), in which the binary codes are randomly formed and used to present the transmission data, in which the states 0 and 1 are represented by |DB〉 and |BD〉, respectively. Finally, the eavesdropper and signal accuracy are also described.
