Abstract
Lossy one-dimensional (1-D) magnetophotonic crystals (MPCs) consisting of a highly absorptive magnetic layer and two types of dielectric layers are assumed. Magnetic medium is a TbFeCo alloy mostly used for application in magneto-optical data storage disks. Bringing to account the problematic effects of optical loss on the photonic band gap of MPC, two compensative approaches are introduced to attain proper modified PBGs regarding operational wavelength of the structure. Both approaches, gap-shift and resonance-tuning, utilize non-quarter-wave design of MPC structures, and although each one is non-conventional in the realm of MPC design, they offer well suited solutions for the problem. Having applied these approaches, we obtained enhanced magneto optic Kerr effect accompanied with desired optical response.
