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.

Multi-wavelength optical network security generated by modified add-drop filter

Surachai Tunsiri, Saysamone Soysouvanh, Somsak Mitatha +2 more

The multi-wavelength optical network security system generated by using an optical nonlinear material within the modified add-drop optical filter for network security is proposed. By using the dark-bright nonlinear pulse control, the optical multi-wavelength can be constructed and applied to securely transport within the network. The advantage is that the dark and bright nonlinear pair (components) can securely propagate for long distance without electromagnetic interference. In operation, the optical intensity from modified add-drop optical filter is established.
