The course is intended to expose undergrads and junior graduates to the basic principles of quantum physics and its application in engineering fields, such as lasers, solid state, etc. It is intended to be an introductory course to "Lasers", "Solid-state", "Quantum Electronics", "Nonlinear Optics", and "Electr. & Opt. Properties of Materials", and to cover the needs of most of departments in the School of Engineering.
