Course Title: Nonlinear Optics Course Code: to be decided later Credit Units: 4 Level: U.G. Statistical Mechanics # 1 Course Objectives: Student should be able to understand simple evaluations of nonlinear phenomena in optics. Examples will be directed toward applications within optical communications, and lasers. 2 Prerequisites: NIL 3 Student Learning Outcomes: Student shall be able to formulate a well-defined and physically significant problem within the main areas of nonlinear optics. Describe the photo induced refractive index using the induced polarization and apply the corresponding wave equation to explain transmission of short optical pulses. Differentiate between Raman and Brillouin scattering and explain these phenomena using susceptibility and the induced polarization. Describe propagation of wave in an-isotropic materials, and describe phase-matching conditions in such materials.
