Course Objective:Understanding materials is integral to the design of modern optical systems. This course introduces students to the properties of engineered optical materials such as glasses, single-crystals, transparent ceramics and polymers. It is not intended as a catalog of materials and properties, but rather, it is structured to give a clear physical rationale for performance optimization in various applications. We analyze the effect of the electronic and crystallographic properties of the lattice and that of defects (dopants, impurities and extended defects) on the generation and propagation of light. We also study how fabrication methods impact the performance of optical materials. Examples in this class cover a wide range of applications including nanophosphors for medical applications, optical coatings for high precision interferometers, glass, crystalline and ceramic laser gain media for high power and femtosecond generation, scintillator based nuclear detectors, transparent armors, and photo-engineered polymers for passive optics.
