OptiSystem is an optical communication system simulation package for the design, testing, and optimization of the links between the optical networks. In modern communications systems, conventional wires are being replaced by optical fibers because these have high bandwidth and hence offers high data rates and are immune to noise.

Charles Kuen Kao is known as the “father of fiber optic communications” for his discovery in the 1960s of certain physical properties of glass, which laid the groundwork for high-speed data communication in the Information Age.Before Kao's pioneering work, glass fibers were widely believed to be unsuitable as a conductor of information because of excessively high signal loss from light.
In this thesis, digital signal processing (DSP) algorithms are studied to compensate for physical layer impairments in optical fiber coherent communication systems.
The dissertation is dedicated to DSP techniques for the advanced fiber-optic systems. It consists of two main research topics. The first topic is about Fast-orthogonal frequency-division multiplexing (OFDM) — a variant OFDM scheme whose subcarrier spacing is half of that of conventional OFDM.
This thesis describes the methods and processes of generating tunable single wavelength and dual-wavelength fiber lasers by using two different types of gain media. They are erbium doped fiber (EDF) and semiconductor optical amplifier (SOA) with each of them working as near to homogeneous and inhomogeneous broadening transition gain media respectively.
The optical fibre communications industry has been facing some significant challenges in recent years. As transmission rates in optical networks constantly increase, and with the concerns over the energy consumption of communication networks becoming ever more relevant, there is a compelling argument for adopting new techniques for the implementation of signal processing of communication signals.

The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to.
ANALYSIS AND COMPENSATION OF NONLINEAR IMPAIRMENTS IN FIBER-OPTIC COMMUNICATION SYSTEMS BY XIAOJUN LIANG, M.A.Sc. a thesis submitted to the department of electrical and computer engineering and the school of graduate studies of mcmaster university in partial fulfilment of the requirements for the degree of Doctor of Philosophy.
With the thesis option of the M.S. in Optical Sciences degree program, the student must complete a minimum of 32 units of University of Arizona graduate credit in optics or optics-related courses, including eight units of OPTI 910: Thesis and at least two units of optics laboratory courses.Most graduate courses are three units, so a typical student would take eight or nine academic courses and.
Fiber-optic in Communication Fiber-optics are tiny threads of glasses that are arranged in optical cables to transmit light signal which relay information from one end to another. Fiber-optic is used in communication to enable transmission of information over long distances with minimal disruption and loss of data and hence widely used all over the world.
Optical fiber has changed the world by providing millions of kilometers of telecommunication fiber that have transformed how we communicate. But beyond telecommunications, optical fibers are making enormous impacts on both sensing applications and high-power lasers. The requirements imposed by these non-telecom applications have resulted in a new subset of custom-tailored optical fibers.
Tunable laser module for fibre optic communications This thesis deals with the design, realisation, and testing of the wavelength tunable 1540-nm laser prototypes that are intended for fibre optic communications. The short external cavity laser uses an electrically controlled silicon micromachined Fabry-Perot interferometer (FPI) device as.
We have an open position for a Ph.D. student in the area of fiber-optic communications based on nonlinear Fourier transforms (NFTs). The focus of this position is on analyzing and mitigating the impact of real-world impairments on NFT-based fiber-optic transmission systems.
