Synopsis:

My research focuses primarily on the integration of magnetic and optical materials with standard platforms to allow the development of practical devices and systems.  In photonics, this includes the integration of magnets, magneto-optical garnets waveguides, and nanostructures for magnetophotonic crystals with semiconductor platforms for isolator and sensor applications.  In magnetics, Stadler is working on magnetic nanowires for magnetoelectronics (including hard drive heads) and acoustic sensor applications.
