Abstract

A generation of optical capsules and tweezers within a modified optical add-drop filter known as PANDA ring resonator with a new concept is proposed. By using dark and bright solitons, the orthogonal tweezers can be formed within the system and observed simultaneously at the output ports. Under the resonant condition, the optical capsules and tweezers generated by dark and bright soliton pair corresponding to the left-hand and right-hand rotating solitons (tweezers) can be generated. When a soliton is interacted by an object, an angular momentum of either bright or dark tweezers is imparted to the object, in which two possible spin states known as tweezer spins are exhibited. Furthermore, an array of molecular capsules and spins, i.e., trapped molecules can be generated and detected by using the proposed system, which can be used to form large scale tweezer or capsule spins. In application, the trapped molecules can be moved and rotated securely to the required destinations, which can be useful for many applications, especially, in medical diagnosis, therapy and surgery.

SOLITON SPIN IN AN ADD–DROP OPTICAL FILTER FOR LONG DISTANCE SPIN TRANSPORT

C. Teeka, Muhammad Safwan Abd Aziz, Surasak Pipatsart +3 more

A new concept of an optical 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 orthogonal solitons corresponding to the left-hand and right-hand solitons (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 soliton spins are exhibited. Many soliton spins, i.e., many particles, dynamic spin and long distance spin transport using the proposed design are also discussed.

SOLITON SPIN AND WAVE-PARTICLE DUALITY

Somsak Mitatha, S. GLOMEGLOM, C. Teeka +2 more

By using the optical add-drop filter which is formed by a microring resonator, and after a dark soliton pulse is fed into an input port of the add-drop filter, the orthogonal soliton pair (dark and bright solitons) can be formed within the system and detected simultaneously at the output ports. Under the resonant condition, the conversion of dark and bright solitons corresponding to the left-hand and right-hand soliton orientations can be generated and seen. 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 exhibited and confirmed by the helical phase presentation. In application, the train of orthogonal solitons, i.e. many solitons (photons) with slightly different wavelengths can be generated by using the modified add-drop filter, which is available for many soliton spins and long distance spin transport investigations.

Whenever a soliton(photon) is absorbed by an object, an angular momentum of either +h or −h is imparted to the object, in which two possible soliton states known as soliton spins are exhibited and confirmed by the helical phase presentation.

A Novel Multi Optical Tweezers Generation using a Dark Soliton for Transportation Atom/Molecule

Nithiroth Pornsuwancharoen, p Sanpoang

Abstract We propose a novel system of the optical tweezers array generation using dark soliton control within and add/drop filter control light by light. The dynamic tweezers are generated within an add/drop filter, where the number of tweezers within the add/drop filter can be tuned and amplified. The smallest tuned tweezers width are 0.02-0.05 nm are achieved, where the number of tweezers are 10-20 in an array. We have also theoretically shown that the dynamic tweezers can be controlled and tuned by varies the couple coefficient (k) between 0.1-0.9 and the radius of ring resonator between 10-20 |j.m, which is available for trapping and transportation in the communication up­link system via a add/drop filter. In application, the transmission of tweezers with different molecules and wavelengths can be performed within the transmission link, which is available for high density molecular transportation for wireless communication in near future.

By using the polarization mode identification, the entangle photon states of the tweezers can be formed, which is allowed to form the molecular quantum transmission. The number of tweezers within the add/drop filter can be tuned, amplified and quantum states of the molecule identified. The number of tweezers of 50–100 in an array with the smallest tweezer width of 2 nm is generated and achieved. We have also theoretically shown that the quantum multioptical tweezers can be controlled and tuned by varies the couple coefficient (κ) between 0.1 and 0.9, with ring resonator radii between 10 and 20 μm, which is available for molecule trapping and transportation in the communication uplink system via the add/drop filter.

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

Xaythavy Louangvilay, Somsak Mitatha, Masahiro Yoshida +2 more

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.
