We propose an approach for the design of resonant cavities employed in magnetophotonic crystal (MPC) circulators and isolators. Starting from the analysis of a model circularly symmetric cavity, we show how to obtain a significant splitting of the eigenfrequencies of the two counterrotating cavity modes without introducing subdomains magnetized in opposite directions. Using the multiple-scattering method extended to handle uniaxial gyrotropic materials, we demonstrate numerically an MPC circulator working in a uniform external magnetic field.

  15. Faraday rotation of 10 deg/μm has been measured at λ=620 nm in BIG thin films , so a few deg/μm, or g~0.05-0.1, seem accessible in the infrared range. Moderate SEMF (<0.5 T) suffices for BIG saturation .
