Abstract

We proposed a concept of cryptography using dark-bright soliton conversion be- haviors within a nonlinear ring resonator, in which the orthogonal soliton is established among the soliton conversion. A new model of add/drop fllters is modifled which is 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. The entangled solitons (photons) can be formed in the same way of the entangled photons, but in this case the entangled soliton pair is gained more power that gives the advantage of long distance communication.

We present a new concept of quantum cryptography using dark-bright soliton conversion behaviors within a nonlinear ring resonator, in which the orthogonal soliton is established among the soliton conversion. A new model of add/drop filters is modified which is known as a PANDA Ring resonator is proposed. The entangled soliton(photon) can work in the same way of the entangled photon, but in this case the entangle soliton is gained more power that give the advantage of long distance quantum communication. In application, the high capacity quantum communication is also variable by using the multivariable entangled solitons.

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.

Photon Switching using Nonlinear PANDA Ring Resonetor

Sa-nga Songmuang, Suphanchai Punthawanunt, Somsak Mitatha +1 more

We propose a new system of an all optical switching system using an optical add/drop filter consisting of two nano ring resonators. The dynamic behavior of dark-bright soliton collision within the modified add/drop optical filter device, which it is known as PANDA ring resonator. By using the dark-bright soliton conversion control within the PANDA ring, the obtained output signals can be attenuated and used to perform the single photon switching, which is capable for security code application. Results obtained have shown that the random binary codes based on a single photon switching can be formed by using the polarized light components, dark and bright solitons, whereas the single photon switching codes can be obtained by using the attenuated dark-bright soliton conversion signals output signals.

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.
