Coexistence of large Faraday rotation and high transmittance in magnetophotonic crystals with multi-cavity structures

Far infrared Faraday rotation effect in one-dimensional microcavity type magnetic photonic crystals

“…An intriguing method is to introduce more defects in the MPC [10,16]. In this design, the relatively sharp transmission peaks form flat-top transmission bands, and the transmittance is improved.…”

“…Microcavity type MPCs present a comparable Faraday rotation effect to the previous structures [11]. Those structures were quickly prepared and addressed by both the experiments and further calculations [12][13][14][15][16], and excellent agreement between the experiments and calculations was achieved in Ref. [17].…”

Slow light phenomenon and extraordinary magnetooptical effects in periodic nanostructured media

“…At the same time, the system of densely packed dielectric spheres with voids filled with magnetic fluid represents a three-dimensional MPC [7]. In the end of the previous century the effect of the Faraday rotation enhancement in MPCs was theoretically predicted and experimentally observed [5][6][7][8][9]. The one-dimensional MPCs made of bismuth iron garnets for magnetic layers and gadolinium gallium garnet for non-magnetic dielectric layers were used.…”

Temporal coupled mode analysis of one-dimensional magneto-photonic crystals with cavity structures

“…The decrease is resulted from the fact that the transmission resonance of a single-cavity structure is divided into two, due to the slightly different refractive indices of the right-hand and the lefthand circular polarizations. The transmission (reflection) of a single-cavity MPC can be improved by using double-cavity and multiple-cavity structures without any loss of Faraday (Kerr) rotation [24][25][26][27][28]. The key of the improvement is the overlapping of the transmission peaks of the opposite circular polarizations of different optical resonances.…”
