Course content
Part I - Fundamentals 1. Intruduction to optical communications, fiber optics vs. conventional transmission lines, typical fiber-optic link; optical encoding of information, carrier, modulation, sidebands; temporal and spectral aspects; bit error rate, crosstalk, inter-symbol interference, eye diagram. 2. Modulation and demodulation of intensity/phase/frequency, homodyne and heterodyne detection, carrier recovery, phase lock loop; power spectral density, timing jitter and phase noise, Allan variance. 3. Multiplexing, wavelength-, polarization-, and spatial-division. 4. Low light limit, statistics, signal-to-noise ratio, attenuation and amplification. Part II - Low level / Technology 5. Optical fibers (TIR,PBG,MM,SM,PM), modes, dispersion and disp.compensation, losses, polarization; nonlinear effects, fiber amplifiers, spont.emission, noise figure; materials and manufacturing. 6. Integrated devices, technology, hybrid IO; couplers, splitters, freq.filters+microresonators, AWG, modulators: electro-optical effects and free carier injection; IN/OUT coupling, SOI vs telecom fiber coupling problem; splicing, connectors. 7. Sources: LED, SLED, LD, VCSEL, DFB, DBR, monolithic vs hybrid, direct vs indirect band gap; P-I curve, spectral properties, modulation speed, statistics and noise; quantum wells and dots. 8. Detectors: photodiodes PN, PIN, APD, single-photon detectors; sensitivity, bandwidth, noise, NEP, linearity. Part III - High level 9. Network topology and distances; passive networks vs repeaters vs amplifiers. 10. Transmitters (direct vs ext.modulator) and receivers, incoherent and coherent receivers. 11. Measurement methods, dispersion measurement, optical time-domain reflectometry. 12. Speed/capacity limitations, bandwidth-distance product, record speeds.
