227-0301-00L | Optical Communication Fundamentals | 6 credits | 2V + 1U + 1P | J. Leuthold | |
Abstract | Transmitters and receivers are the basic building blocks of communication links. In this lecture we discuss the path of an analog signal in the transmitter to the digital world in an optical communication link and back to the analog world at the receiver. The lecture is organized to cover the fundamentals of all important optical and optoelectronic components in a fiber communications system. | ||||
Objective | Fundamentals of optical communications systems with an emphasis on transmitters and receivers. | ||||
Content | Chapter 1: Introduction: Analog/Digital Conversion, The Communication Channel, Shannon Channel Capacity. Chapter 2: The Transmitter: Components of a Transmitter, The Spectrum of a Signal, Optical Modulators, Modulation Formats. Chapter 3: Signal-to-Noise Ratio, Intersymbol Interference, Electronic Coding. Chapter 4: Multiplexing techniques (WDM/FDM, TDM, OFDM, Nyquist Multiplexing, OCDMA). Chapter 5: Optical Amplifiers (Semiconductor Optical Amplifiers, Erbium Doped Fiber Amplifiers, Raman Amplifiers). Chapter 6: The Receiver: pin-Photodiodes, Polarisation Demultiplexing, Phase Estimation, Clock Recovery. Chapter 7: Noise: Noise Mechanisms, Photocurrent Noise, Thermal Noise, Electronic Amplifiers Noise, Optical Amplifier Noise. Chapter 8: Receiver and Detector Errors: Detection Errors of On-Off Keying, Detection Errors of M-Ary Signals, Direct-, Heterodyne and Homodyne Reception. | ||||
Lecture notes | Lecture notes are handed out. | ||||
Prerequisites / Notice | Fundamentals of Electromagnetic Fields & Bachelor Lectures on Physics (see Bsc ITET). | ||||
227-0655-00L | Nonlinear Optics | 6 credits | 2V + 1U | J. Leuthold | |
Abstract | Nonlinear Optics deals with the interaction of light with material, the response of material to light and the mathematical framework to describe the phenomena. As an example we will cover fundamental phenomena such as the refractive index, the electro-optic effect, second harmonic generation, four-wave mixing or soliton propagation and others. | ||||
Objective | The important nonlinear optical phenomena are understood and can be classified. The effects can be described mathematical by means of the susceptibility. | ||||
Content | Chapter 1: The Wave Equations in Nonlinear Optics Chapter 2: Nonlinear Effects - An Overview Chapter 3: The Nonlinear Optical Susceptibility Chapter 4: Second Harmonic Generation Chapter 5: The Electro-Optic Effect and the Electro-Optic Modulator Chapter 6: Acousto-Optic Effect Chapter 7: Nonlinear Effects of Third Order Chapter 8: Nonlinear Effects in Media with Gain | ||||
Literature | Lecture notes are handed out. | ||||
Prerequisites / Notice | Fundamentals of Electromagnetic Fields (Maxwell Equations) & Bachelor Lectures on Physics | ||||
227-0955-00L | Seminar in Electromagnetics | 3 credits | 2K | J. Leuthold, C. Hafner | |
Abstract | Selected topics of the current research activities of the IFH and closely related institutions are discussed. | ||||
Objective | Have an overview on the research activities of the IFH. | ||||
227-1101-00L | How to Write Scientific Texts in Engineering Sciences Strongly recommended prerequisite for Semester Projects and Master Theses at D-ITET (MSc BME, MSc EEIT, MSc EST). | 0 credits | J. Leuthold | ||
Abstract | The 2 to 3 hour lecture will cover the basics of writing a scientific text. The focus will be on the structure and elements of scientific text and not on the language. | ||||
Objective | Knowledge on structure and content of a scientific text. | ||||
Content | Topic 1: Structure of a Scientific Text Topic 2: The Title, the author list, the abstract, State-of-the Art, the "in this paper" paragraph, the scientific part, the summary Topic 3: Equations, Figures Topic 4: Citation rules | ||||
