Combining scattering-scanning near-field optical microscopy (s-SNOM) with infrared synchrotron micro-spectroscopy we determine the magnetic near-field modes of an infrared linear antenna by measuring the electric field of its electro-magnetic dual, the linear slot antenna.
The precise characterization of the ultrafast electronic response in a metallic nanostructure is achieved using a combination of spectrogram measurement of collinear interferometric second-harmonic scattering and treatment of Frequency Resolved Optical Gating (FROG). The plasmon dephasing dynamics have been resolved with multiple time-scales.
Many ultra-bright light-emitting diodes (LEDs), especially the white LEDs, are being actively developed for solid-state lighting and many other commercial applications. Hence, it is important to evaluate and understand the failure mechanisms that affect the performance characteristics and lifetimes of these new LEDs. This study concerns the humidity effect on the degradation of GaN-based packaged...
