Thermal sensors based on ytterbium-erbium doped nano-glassceramics
Lead-fluoride nano-glassceramics doped with ytterbium and erbium have been developed and synthesized. The influence of heating on the green up-conversion luminescence of erbium has been experimentally investigated. Nano-glassceramics are promising candidates for temperature sensors.
Room temperature ZnSe/ZnCdSe bistable self‐electro‐optic effect device operating at 488 nm
Optical bistability at room temperature has been observed for the first time in a II‐VI semiconductor self‐electro‐optic effect device fabricated by molecular beam epitaxy. The optical switch is based on a ZnSe/ZnCdSe multiple quantum well structure situated within a p‐n junction and the devices operate at 488 nm in the blue‐green spectral region.
Investigations of dielectric gratings using electrodynamic models based on volume integral equations
Eigenmodes of planar and cylindrical dielectric gratings (DGs) and electromagnetic wave scattering from multiplayer DGs are investigated. The DG characteristics are calculated using numerical-analytical solution of integral equations (IEs).
