Ferromagnetic Magnetooptical Oxides for Nonreciprocal Photonic Devices Caroline A. Ross, Massachusetts Institute of Technology, DMR 1104912

Oxides offer a wide range of useful electrical, optical and magnetic properties which can be incorporated into electronic devices to extend their functionality. Magnetic oxides which are magnetooptically active are an essential component of photonic components such as optical isolators or magnetooptical modulators.

This project develops thin film magnetooptical materials based primarily on perovskites and understanding how the magnetic and optical properties can be controlled by the substitution of ions onto the A and B sites and the presence of vacancies on the oxygen sites.

Broader aspects include the training of a graduate student, MehmetOnbasli, and an undergraduate, Alexandra Manick. Aspects of this work are incorporated into the undergraduate and graduate curriculum, which will be disseminated to the public via the MIT OpenCourseWare initiative, and linked to the microphotonics industry. We contributed to a summer teachers program and the ACCESS program for minority undergraduates.

The magnetooptical devices made possible from this project could be transformative in the field of optical computing devices.
