Optimised nano-engineered 1-D magnetophotonic crystals for integrated-optical modulators

The optimization of multilayer ID megnetophotonic crystals with mulitple nano-engineered defects enables novel practical photonics applications. The properties of several optimized structures suitable for infrared intensity modulators are discussed. A novel approach to the design of integrated multi-channel WDM/DWDM transmission loss equalizers is proposed. We also show the effect of material absorption on the spectral properties of magnetic phtonic crystals, which is a factor of primary importance for the design of short-wavelenght infrared modulators

Effect of Oblique Light Incidence on Magnetooptical Properties of One-Dimensional Photonic Crystals

We have investigated the magnetooptical properties of one-dimensional magnetic photonic crystals for the case of oblique light incidence. We developed a theoretical model based on the transfer matrix approach. We found several new effects such as transmittance resonance peak shift versus external magnetic field and the Faraday effect dependence on the incidence angle.We discuss several possible one-dimensional magnetic photonic crystals applications for the optical devices

Experimental investigation of magnetic circular dichroism spectrum and stress induced optical activity in a single-defect photonic crystal

Experimental investigation results for the magnetic circular dichroism spectrum (MCD) of a photonic crystal (PC) are presented. We found that in the vicinity of the transmission peak within the photonic bandgap and also near the bandgap edges, the circular dichroism is measurable even in the absence of any applied magnetic field. The application of magnetic field leads to generating an additional MCD signal measurable at the wavelengths near the “defect mode” transmittance line

Technological challenges of 1-dimensional magnetic photonic crystals

Visible-region magnetic photonic crystals (MPC) designed for higher-order bandgap operation have been proposed to overcome the technological restrictions originating from the strong thickness dependency of the individual magnetic layer properties observed in MPC structures
