Aim: The course will provide the students with a solid understanding of the physics of advanced semiconductor optical devices. Starting from a detailed and fundamental description of the semiconductor laser and semiconductor optical amplifier a number of devices relevant to optical communication systems will be treated. Through the examples the relevant physical mechanisms are highlighted and analysed. Topics from the actual research at the COM center will be used and the course may lead to experimental as well as theoretical special courses or Master projects at COM.
