The Reflectance Spectra of Photonic Crystals with Embedded Ferrite Inclusions

Abstract: Results of optical properties investigations of photonic crystals, filled by ferrites, are presented. The photonic crystals consist of amorphous SiO2 spherical nanoclusters. Pores of the crystals were filled by ferrites , where . Reflectance spectra were studied in visible range. It was shown that the reflectivity of the fabricated magnetophotonic crystals increases up to 80% under magnetization.

“…The mechanism of the formation of enhanced generation of the third harmonic can be associated with the effect of a decrease in the group velocity of pump radiation propagation in the photonic crystal when operating near the band gap and with the effect of structural light focusing in the photonic crystal bulk. [19][20][21][22] Structural light focusing in the opal matrices l leads to the formation of the regions with high intensity of optical radiation. Exactly when the pump wavelength coincides with the photonic crystal band gap position, high-intensity optical field regions are localized at the crystal globule center; in this case, the intensity of formed optical field caustics feature a maximum intensity exceeding the 7, 1750038 (2017) radiation intensity in a homogeneous quartz medium by an order of magnitude.…”
