  Magneto-Optic Photonic Crystals (MOPC) used in low dimension lasers whereby
acting as Faraday rotators capable of 45o rotation where insertion loos is
compensated by photoluminescence effect are of significant interest. In low
dimension sensors MOPCs act as optical filters to selectively detect only
lights at certain wavelengths. Combined with the photoluminescence effect,
sensors may be designed capable of detecting signals with extremely low
intensity, thus high quantum efficiency. In this work, MOPC with various Erbium
dopant concentrations, acting as photoluminescence center, were modelled under
high pumping power regime associated to 0.985 inversion population to identify
the minimum Erbium concentration and number of layers for the target 45 degrees
FR, 0.9 transmittance and minimal ellipticity at the resonance wavelength
1531nm. Further optimization of Magneto-optical (MO) properties versus the
microcavity position within the MOPC was investigated. An optimum multilayered
configuration and composition was identified with a reduction in both erbium
concentration and total thickness compared to what was reported previously
without compromising the target MO properties.
