Abstract

A system of microring resonator (MRR) is presentedto generate extremely narrow optical tweezers. An add/dropfilter system consisting of one centered ring and one smaller ringon the left side can be used to generate extremely narrow pulseof optical tweezers. Optical tweezers generated by the dark-Gaussian behavior propagate via the MRRs system, where theinput Gaussian pulse controls the output signal at the drop portof the system. Here the output optical tweezers can be connectedto a quantum signal processing system (receiver), where it can beused to generate high capacity quantum codes within series ofMRR’s and an add/drop filter. Detection of the encoded signalsknown as quantum bits can be done by the receiver unit system.Generated entangled photon pair propagates via an opticalcommunication link. Here, the result of optical tweezers with fullwidth at half maximum (FWHM) of 0.3 nm, 0.8 nm and 1.6 nm,1.3 nm are obtained at the through and drop ports of the systemrespectively. These results used to be transmitted through aquantum signal processor via an optical computer networkcommunication link.

Generation of potential wells used for quantum codes transmission via a TDMA network communication system

ABSTRACT This paper proposes a technique of quantum code generation using optical tweezers. This technique uses a microring resonator made of nonlinear fibre optics to generate the desired results, which are applicable to Internet security and quantum network cryptography. A modified add/drop interferometer system called PANDA is proposed, which consists of a centred ring resonator connected to smaller ring resonators on the left side. To form the multifunction operations of the PANDA system—for instance, to control, tune and amplify—an additional Gaussian pulse is introduced into the add port of the system. The optical tweezers generated by the dark soliton propagating inside the PANDA ring resonator system are in the form of potential wells. Potential well output can be connected to the quantum signal processing system, which consists of a transmitter and a receiver. The transmitter is used to generate high‐capacity quantum codes within the system, whereas the receiver detects encoded signals known as quantum bits. Therefore, an entangled photon pair can be generated and propagated via an optical communication link such as a time division multiple access system. Here, narrower potential wells with a full‐width half‐maximum of 3.58 and 9.57 nm are generated at the through and drop ports of the PANDA ring resonator system, respectively, where the amplification of the signals occurs during propagation inside the system.

Generation of discrete frequency and wavelength for secured computer networks system using integrated ring resonators

Iraj Sadegh Amiri, k. Sarkhanlou, Ali Nikoukar +3 more

In this study, a system of discrete optical pulse generation via a series of microring resonator (MRR) is presented. Chaotic signals can be generated by an optical soliton or a Gaussian pulse within a MRR system. Large bandwidth signals of optical soliton are generated by input pulse propagating within the MRRs, which can be used to form continuous wavelength or frequency with large tunable channel capacity. Therefore, distinguished discrete wavelength or frequency pulses can be generated by using localized spatial pulses via a networks communication system. Selected discrete pulses are more suitable to generate high-secured quantum codes because of the large free spectral range (FSR). Quantum codes can be generated by using a polarization control unit and a beam splitter, incorporating to the MRRs. In this work, frequency band of 10.7 MHz and 16 MHz and wavelengths of 206.9 nm, 1448 nm, 2169 nm and 2489 nm are localized and obtained which can be used for quantum codes generation applicable for secured networks communication.

Abstract We propose a new system of quantum cryptography for internet security using Gaussian pulses propagating within a nonlinear ring resonator system, quantum processor and a wavelength router.To increase the channel capacity and security, the multiplexer is operated incorporating a quantum processing unit via an optical multiplexer.

The reference states can be recognized by using the cloning unit, which is operated by the add/drop filter, where the communication between Alice and Bob can be performed. The results obtained have shown that the correlated photons can be generated and formed the entangled photon pair, which is allowed to form the secret key between Alice and Bob.

Quantum dense encoding can be performed by output signals of selected wavelengths incorporated to a polarization control system. Therefore dark and bright optical soliton pulses with different time slot are generated. They can be converted into digital logic quantum codes using a decimal convertor system propagating along a wireless networks. Results show that multi soliton wavelength, ranged from 1.55m to 1.56m with FWHM and FSR of 10 pm and 600 pm can be generated respectively.
