This book was released on 2014-08-27 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The title explain new technique of secured and high capacity optical communication signals generation by using the micro and nano ring resonators. The pulses are known as soliton pulses which are more secured due to having the properties of chaotic and dark soliton signals with ultra short bandwidth. They have high capacity due to the fact that ring resonators are able to generate pulses in the form of solitons in multiples and train form. These pulses generated by ring resonators are suitable in optical communication due to use the compact and integrated rings system, easy to control, flexibility, less loss, application in long distance communication and many other advantages. Using these pulses overcome the problems such as losses during the propagation, long distances, error detection, using many repeaters or amplifiers, undetectable received signals, pulse broadening, overlapping and so on. This book show how to generate soliton pulses using ring resonators in the micro and nano range which can be used in optical communication to improve the transmission technique and quality of received signals in networks such as WiFi and wireless communication.
Book Synopsis Optical Soliton Communication Using Ultra-Short Pulses by : Iraj Sadegh Amiri
Download or read book Optical Soliton Communication Using Ultra-Short Pulses written by Iraj Sadegh Amiri and published by Springer. This book was released on 2015-05-07 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief analyzes the characteristics of a microring resonator (MRR) to perform communication using ultra-short soliton pulses. The raising of nonlinear refractive indices, coupling coefficients and radius of the single microring resonator leads to decrease in input power and round trips wherein the bifurcation occurs. As a result, bifurcation or chaos behaviors are seen at lower input power of 44 W, where the nonlinear refractive index is n2=3.2×10−20 m2/W. Using a decimal convertor system, these ultra-short signals can be converted into quantum information. Results show that multi solitons with FWHM and FSR of 10 pm and 600 pm can be generated respectively. The multi optical soliton with FWHM and FSR of 325 pm and 880 nm can be incorporated with a time division multiple access (TDMA) system wherein the transportation of quantum information is performed.

Download or read book Integrated Micro-Ring Photonics written by Iraj Sadegh Amiri and published by CRC Press. This book was released on 2016-12-08 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micro-ring resonators (MRRs) are employed to generate signals used for optical communication applications, where they can be integrated in a single system. These structures are ideal candidates for very large-scale integrated (VLSI) photonic circuits, since they provide a wide range of optical signal processing functions while being ultra-compact. Soliton pulses have sufficient stability for preservation of their shape and velocity. Technological progress in fields such as tunable narrow band laser systems, multiple transmission, and MRR systems constitute a base for the development of new transmission techniques. Controlling the speed of a light signal has many potential applications in fiber optic communication and quantum computing. The slow light effect has many important applications and is a key technology for all optical networks such as optical signal processing. Generation of slow light in MRRs is based on the nonlinear optical fibers. Slow light can be generated within the micro-ring devices, which will be able to be used with the mobile telephone. Therefore, the message can be kept encrypted via quantum cryptography. Thus perfect security in a mobile telephone network is plausible. This research study involves both numerical experiments and theoretical work based on MRRs for secured communication.

Download or read book Microring Resonator for Secured Optical Communication written by Iraj Sadegh Amiri and published by CreateSpace. This book was released on 2014-07-21 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel system of dark soliton array (DSA) for secured communication generated by using the multiplexed dark soliton pulses is proposed. The multi soliton pulses with relevant parameters are input into the micro ring resonators system with the radii of 10 µm and 5 µm, where the dynamic dark solitons can be controlled and generated. The DSA are obtained by using a series micro ring resonators with parameters where in the wavelength range of 1.56, 1.58 and1.60. For security applications, the DSA can be tuned and amplified. Thus, the use of DSA for high capacity which can be realized by using proposed secured system. In transmission, the long distance link of the multi variable network can be performed by this DSA.

Download or read book Soliton Coding for Secured Optical Communication Link written by Iraj Sadegh Amiri and published by Springer. This book was released on 2014-07-24 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear behavior of light such as chaos can be observed during propagation of a laser beam inside the microring resonator (MRR) systems. This Brief highlights the design of a system of MRRs to generate a series of logic codes. An optical soliton is used to generate an entangled photon. The ultra-short soliton pulses provide the required communication signals to generate a pair of polarization entangled photons required for quantum keys. In the frequency domain, MRRs can be used to generate optical millimetre-wave solitons with a broadband frequency of 0–100 GHz. The soliton signals are multiplexed and modulated with the logic codes to transmit the data via a network system. The soliton carriers play critical roles to transmit the data via an optical communication link and provide many applications in secured optical communications. Therefore, transmission of data information can be performed via a communication network using soliton pulse carriers. A system known as optical multiplexer can be used to increase the channel capacity and security of the signals.

Download or read book Microring Resonators written by A. Afroozeh and published by Createspace Independent Publishing Platform. This book was released on 2015-12-03 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study starts with design considerations, the functional behaviour, and key characteristics of the microring resonator and add/drop ring resonators allowing the performance of higher order filters. For nonlinear materials the basic equations to describe the formation and propagation of different types of optical solitons are well known. The resonance condition is satisfied when the circumference of the microring resonators, or generally the round-trip length, is equal to an integer multiple of the optical wavelength inside the medium. The chaotic behaviour of the multi output signals generated from these devices can be filtered using appropriate parameters. Optical chaos is observed in many non-linear optical systems. One of the most common examples is a microring resonator. Chaotic behaviour has been considered as a nonlinear property in physics, electronics and communication. Soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed. Among all the types of solitons, optical vector solitons draw the most attention due to their wide range of applications, particularly in generating ultrafast pulses and light control technology. Dark solitons are much less stable due to the cross-interaction between the two polarization components. The bus waveguides of the microring resonator are cladded by silica, which serves both to improve modal con nement and facilitate wafer bonding for structural support. The source of nonlinear reaction is related to harmonic motion of bound electrons under the influence of an applied field. The total polarization P induced by electric dipoles is not linear in the electric field. The extent that the signal degrades depends on the purity of the glass and the wavelength of the transmitted light. This refractive index variation is responsible for the nonlinear optical effects of self-focusing, self-phase modulation and modulation instability, and is the basis for Kerr-lens mode locking. The quality factor of a resonator is a measure of the sharpness of the resonance. Therefore the optimum fabrication process can be obtained with respect to higher quality factor of the device. The phenomenon of optical bistability within the system arises from a combination of the nonlinearity in the radiation-matter interaction and of a feedback mechanism."
