Generalized treatment of magneto-optical transmission filters

摘要

This work has constructed a model for the theoretical analysis of generalized magneto-optical transmission filters for any relative angle between the light beam and the applied magnetic field. This model was experimentally validated and shows good agreement between the theoretical predictions and experimental spectra. In addition, the value of examining magneto-optical filters for arbitrary angle cases was demonstrated by revealing an optimized filter with an equivalent noise bandwidth of 0.56 GHz, which is approximately a factor of 2 better than those previously reported.
