Description: |
-- Introduction: electromagnetic wave theory, light propagation in optical waveguides, LP modes and their propagation properties. -- Components: laser diodes, modulators, amplifiers, photo detectors, their coonection to optical links. -- Structures of photonic communication nets for application in LAN, MAN, WAN. -- Modulation methods: on-off keying (OOK), PSK, QPSK, 64QAM, and their implementation within the optical domain. -- Use of complex modulation methods, e.g. in high bit rate radio-over-fiber systems (RoF systems), in combination with a high frequency radio channel (millimeter-wave multi-gigabit point-to-point link). -- Important optical communication standards. |
Learning Targets: |
The Students are able to analyze light propagation in waveguides and the effects of absortion and dispersion and to optimize optical fiber channels concerning reduction of these negative properties (multi-mode, single mode, dispersion compensation, 3R amplification). They are able to design optical point-to-point connections using suitable devices and waveguides, taking into account the different requirements for LAN, MAN, and WAN. They understand different multiplex methods (TDM, WDM) and optical modulation methods and are able to design ple fibre optical net structures (e.g. passive optical network, PON) taking into account important standards. |
