Optics is an applied physics area with applications in industry, scientific instrumentation, medicine, astronomy, and future technologies such as quantum computing. The University of Iowa is the home of the Optical Science and Technology Center (OSTC), which is an interdisciplinary center for optics researchers in physics, chemistry, engineering, and other fields. The Department of Physics and Astronomy has experimenters who develop and test new optical devices and materials, as well as experimenters in the fields of plasma, atomic, and molecular physics, who develop scientific instruments based on lasers and optics. Our experimenters have fifteen labs on campus, and we have a theorist. We offer graduate-level courses in modern optics.

We have greatly increased the number of optics faculty and state-of-the-art laboratories in our department. Students interested in optics enjoy a wide range of research possibilities, within the OSTC and with other faculty in the Department as well. With their strong financial support from numerous funding agencies, our faculty members offer students excellent research opportunities. Job placement opportunities are particularly strong for PhD graduates with experience in any of the kinds of optics that our students use.
