Tunable Integrated-Optics Nanoscaled Devices Based on Magnetic Photonic Crystals
Magnetooptical properties of magnetic photonic crystals have been
investigated in the view of their possible applications for the modern
integrated-optics devices. A "transfer matrices" formalism was expanded for the
case of oblique light incidence on the periodic nanoscaled magnetic
multilayered systems. Several new effects such as the Faraday effect dependence
on the incidence angle and the tunability of the bandgap defect modes spectral
location by external magnetic fields were found. Several possibilities of
one-dimensional magnetic photonic crystals applications for the optical devices
are discussed. Initial steps towards the practical implementation of the
proposed devices are reported.Comment: Submitted on behalf of TIMA Editions

Magnetic Photonic Crystals: 1-D Optimization and Applications for the Integrated Optics Devices
The optimization of multilayer one-dimensional (1-D) magnetophotonic crystals (MPCs) with multiple phase shifts, enabling their design to be tailored to practical photonics applications, is reported. The properties of sample optimized structures suitable for application in infrared intensity modulators are discussed. A novel scheme of high-resolution magnetic field sensing using MPCs is proposed. The effect of material absorption on spectral properties is shown
Novel Magnetic Photonic Crystal Structures for Magnetic Field Sensors and Visualizers
Optimized one-dimensional (1-D) magnetophotonic crystals greatly increase the sensitivity of magnetooptical sensors, which are widely used in magnetooptical imaging to observe the magnetic domain patterns in magnetic materials, to observe the vortex states in superconductors, to detect small bits in magnetooptical recording media, to visualize defects in ferromagnetic objects, and to measure the value and spatial distribution of stray magnetic fields. This paper examines the properties of such devices operating in the optimized reflection (doubled Faraday rotation) mode and discusses the use of 1-D magnetophotonic crystals as sensors

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
