Nanoscale infrared spectroscopy with a thermal source: Nano-FTIR

We demonstrate a FTIR system that allows for infrared-spectroscopic nano-imaging with a thermal source (nano-FTIR). Based on super-focusing of thermal radiation with an infrared antenna and strong signal enhancement using an asymmetric FTIR spectrometer, we improve the spatial resolution of conventi...

Description
Summary:We demonstrate a FTIR system that allows for infrared-spectroscopic nano-imaging with a thermal source (nano-FTIR). Based on super-focusing of thermal radiation with an infrared antenna and strong signal enhancement using an asymmetric FTIR spectrometer, we improve the spatial resolution of conventional IR spectroscopy by 2 orders of magnitude.
