Magnetophotonic properties of inverse magnetic metal opals

Nickel inverse opals were fabricated by templating a colloidal crystal. Perfect fcc ordering was confirmed by scanning electron microscopy. Several kinds of magneto-optical effects were studied: linear longitudinal and transversal Kerr effects, nonlinear longitudinal Kerr effect (magnetization-induced second harmonic generation), which were all consistent with the photonic band structure studied by reflectivity spectroscopy.

Advantages of STED-Inspired 3D Direct Laser Writing for Fabrication of Hybrid Nanostructures

We present a new method of additive laser technology referred to as STED nanolithography technique. This technique provides a means for fabrication of 3D dielectric and plasmonic composite nanostructures. The new technology is of the utmost interest for the electronics manufacturing industry, in particular, for formation of specific hybrid (metal–dye) nanostructures, which can be utilized as luminescent markers in biology, medicine, criminalistics, and the trade industry. In the present study, we demonstrate the advantages of STED-inspired nanolithography for fabrication of metallic and hybrid nanostructures. The 3D-scanning setup implemented offers the possibility to form both periodic and aperiodic nanostructured arrays. We show the possibility to decrease substantially the lateral size of the lines formed with the use of STED nanolithography as compared to the direct laser writing (DLW) method. The STED nanolithography technique proposed provides a means for synthesizing metallic nanoparticles in the specified points of the volume of the studied object in vivo. In addition, we demonstrate the synthesis of metallic lines by means of STED nanolithography. Moreover, nanometer spatial precision of positioning of the synthesized nanoobjects is achieved. Therefore, it is possible to obtain significant local enhancement of the emission of luminescent markers (surface enhanced luminescence) at any desired point or area of the sample due to plasmonic enhancement of the electromagnetic fields near the surface of metallic nanostructures.     

A theory of excitation of a planar semiconductor optical waveguide using a diffraction grating: Single-scattering approximation

The problem of excitation of a totally reflecting planar optical waveguide using a coupling diffraction grating in the form of a periodic relief of the waveguide-layer thickness is solved within the single-scattering approximation. The polariton mode in the presence of a quantum well near the waveguide is considered. Based on the developed concepts, the following experimental features of the dependence of the intensity of radiation conducted in the waveguide layer on the angle of incidence of the excitation beam on the coupling diffraction grating are interpreted: the dependence on the mode number, the interference effects in the presence of two coupling diffraction gratings, and the influence of the lower substrate boundary on the thermal behavior of the waveguide structure.
