Basic Optical Processes in Semiconductors: (Stimulated) absorption, spontaneous emission, and stimulated emission. Continuous excitation. Radiative recombination. Exciton recombination. Spontaneous recombination rates and generation rates. Non-radiative recombination. Optical Characterization Methods: reflection spectroscopy, photoluminescence (PL), transmission of light and absorption coefficient. A brief discussion of advanced methods of epitaxial growth. Molecular beam epitaxy. Case of study the laser diode from homojunction to current laser diode heterostructures.
