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...

light emission microcavity lasers
2010/4/6
We study the effect of dynamical tunneling on emission from ray-chaotic microcavities by introducing a suitably designed deformed disk cavity. We focus on its high quality factor modes strongly locali...
STM Light Emission Spectroscopy of Individual Quantum Wells: Measurement of Transport Parameters in Real Space
STM Light Emission Spectroscopy Individual Quantum Wells Transport Parameters Real Space
2010/10/21
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
2010/4/12
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

This work studies the light emission patterns associated with the spatial modulation of the transversal distribution of the current density in a converter cell with a GaAs semiconductor cathode. Such ...
Light Emission From Travelling Space Charge Domains
Light Emission Travelling Space Charge Domains
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...
