Height structure of X-ray, EUV and white-light emission in a solar flare
Sun: fl ares – Sun: X-rays, gamma-rays – Sun: radio radiation – Sun: UV radiation – Acceleration of particles
2011/10/11
The bulk of solar flare emission originates from very compact sources located in the lower solar atmosphere and seen in various wavelength ranges: near optical, UV, EUV, soft and hard X-rays, and gamm...
An arrayed nanoantenna for broadband light emission and detection
optical nanoantennas subwavelength light guiding field enhancement unidirectional emission
2011/8/4
Abstract: We suggest a broadband optical unidirectional arrayed nanoantenna consisting of equally spaced nanorods of gradually varying length. Each nanorod can be driven by near-field quantum emitters...

By spectroscopically analyzing the light emitted from the tip-sample gap of the scanning tunneling microscope (STM), we have investigated the carrier transport as well as the luminescence properties o...
Single Mode Optical Radiation Distribution and Reflectivity Calculations in Novel-Hot Electron Light Emission and Lasing In Semiconductor Heterostructures VCSELs
Optical Radiation Distribution Electron Light Emission Reflectivity Calculations

In this work, we calculate the power reflectivity in vertical cavity surface emitting lasers (VCSELs) using a new method. In VCSELs, the stop band of the reflectivity spectrum should exhibit a dip at ...
Filamentation of Light Emission in an Infrared-Visible Image Converter with a Semiconductor Photodetector
Light Emission Infrared-Visible Image Semiconductor Photodetector

2010/4/16
We report light emission from n-doped GaAs epilayers associated with impact ionization when the device is biased in the negative difference resistance (NDR) regime (F > 3.5 kV cm-1). Spectral distribu...
