Optoelectronics laboratory is focused on properties, applications and characterization of various optical instruments/devices that source, detect and control light. The course participants learn physical processes responsible for generation and detection of light by semiconducting devices, especially modern light sources (LEDs, lasers) and photon detectors. Their properties are characterized experimentally by spectrally - and time-resolved techniques. A lot of emphasis is put on techniques of modulation and transmission of light by nonlinear crystals and glass fibers. Each topic is widely discussed and experimentally illustrated by personally arranged setup. The list of task: 1. Photometry – spectroscopic measurements 2. Photometry – colorimetry 3. Optoelectronic detectors 4. Modulation of light 5. Semiconductor laser 6. Second-harmonic generation 7. Matrix methods in optics. Gaussian beams. 8. Optical fiber
