Beth StadlerSlide presentation part 1 (pdf 460 KB) Slide presentation part 2 (pdf 1.29 MB) This talk will review some fundamentals of magneto-optical functions, materials and devices, as well as present some of the work being performed by Stadler's group at the University of Minnesota. An important application of this work is the ability to equip photonic integrated circuits with important devices that are currently available only as discrete (bulk) components. For years, magneto-optical isolators, in particular, have been cited as some of the most important components in fiber optic systems due to their extension of laser lifetimes and their enhancement of laser signal quality. The latter is especially important as the Internet drives telecommunication systems to increased bit rates and transmission distances. The size, weight and cost of adding an isolator to an optical system will be greatly reduced when the isolator can be integrated directly onto the photonic platform.


Dr. Bethanie Stadler joined the faculty of the Department of Electrical and Computer Engineering at the University of Minnesota as an Assistant Professor in June 2001. Prior to this, she had been a National Research Council Postdoctoral Associate at the USAF Rome Laboratory. In 1990, Dr. Stadler received a B.S. in Materials Science and Engineering from Case Western Reserve University and a Ph.D. from MIT's Department of Materials Science and Engineering in 1994. Dr. Stadler's technical interests are in the areas of magnetic and photonics materials and devices. These include thin film magnets, waveguides, amplifiers, and Faraday rotators, as well as nanostructures for spintronics, recording, acoustic resonators and neurological connects. She was invited to speak at Photonics West 2000 on her work on integrated garnet isolators, and recently won an NSF CAREER award to research isolators and magneto-photonic crystals. Dr. Stadler has co-organized several MRS symposia including "Integrated Magneto-Optics: Materials and Devices" (Spring 1998), "Infrared Applications of Semiconductors" (Fall 1999), and currently "Materials for Magnetic Devices: Magneto-electronics and Recording" (Spring 2001). She will be chairing the Fall 2004 MRS Meeting in Boston. Dr. Stadler's other professional activities include participation on several NSF review panels, founding and directing the MRS Undergraduate Materials Research Initiative, and serving on the program committee of the Joint InterMag/MMM 2000 conference.
