Course review:
Lab examples: 1. Semiconductor sources LED, SLED, LD: V-A and I-L diagrams, spectral density. 2. Optical fibers and waveguides, fiber couplers: dispersion, coupling ratio. 3. Integrated EO modulator: response, half-wave-voltage measurement, modulation and sidebands. 4. Semiconductor photodetectors: responsivity, quantum efficiency, bandwidth. 5. Optical time domain reflectometry: losses in telecommunication link. 6. Wavelength division multiplex based link: crosstalks and bandwidth. 7. Laser narrow linewidth measurement: delayed heterodyne detection. 8. Spectrum and pulse length of fs laser: two-photon absorption in semiconductor. 9. Light-matter interaction: saturated absorption spectroscopy in rubidium vapours. 10. Statistics of light: single photon detectors, independent and bunched photons. 11. Intensity interference and fs-duration measurement: parametric frequency downconversion. 12. Quantum entanglement and nonlocality: Bell's inequalities.
