Abstract
The all-dielectric magneto-optical (MO) structure has garnered considerable interest due to its enhanced MO effect and low ohmic loss compared to the magnetoplasmonic structure. In this study, the effect of Fabry–Perot (F–P) interference on the enhancement of the transverse magneto-optical Kerr effect (T-MOKE) as well as sensing performance is theoretically investigated in a dielectric MO structure composed of cerium-substituted yttrium iron garnet (Ce:YIG) nanopore array coating a nanoporous anodic aluminum oxide (AAO) film standing on an aluminum sheet referred to as the AAO/Al template. The system is particularly interesting because the MO response is significantly enhanced in the position of the F–P interference, in which the T-MOKE signal is close to a 5-fold increase compared with the reference Ce:YIG film. Additionally, the sensing performance shows that the all-dielectric nanopore-based system proposed here provides an alternative to fabricating gas and solution detectors with low ohmic loss.
