Infrared sum-frequency generation (SFG) has been detected with near-field scanning optical microscopy (NSOM) for the first time. SFG NSOM images of a chemical vapor deposited (CVD) disk of zinc selenide were recorded as a function of infrared (IR) wavelengths ranging from 3.1 to 4.4 μm fro...
CAMBRIDGE, Mass., July 28, 2021 — A near-field infrared (IR) nanoscope and spectroscope, custom built by a research team at MIT, can quickly and economically probe the characteristics of diverse materials at the nanoscale. Also known as a scattering-type scanning near-field optical microscope...

The technique is applied to monitor the evolution of the near-field oscillations of infrared gap antennas progressively loaded with metallic bridges of varying size. Our results provide direct experimental evidence that nanoscale infrared near fields can be controlled by antenna loading, which is in ...
Apertureless Scanning Near-Field Infrared Microscopy of a Rough Polymeric Surface Infrared near-field microscopy using an apertureless probe technique has been accomplished to study the surface of a cast copolymer film. Two basic models ... BB Akhremitchev,S Pollack,GC Walker - 《Langmuir》 被引...
Utilizing a broadly-tunable external cavity quantum cascade laser for scattering-type scanning near-field optical microscopy (s-SNOM), we measure infrared spectra of particles of explosives by probing characteristic nitro-group resonances in the 7.1-7.9 mu m wavelength range. Measurements are presented...
Using finite-difference-time-domain simulation, we have studied the near-field effect of Germanium (Ge) subwavelength arrays designed in-plane with a normal incidence. Spectra of vertical electric field component normal to the surface show pronounced resonance peaks in an infrared range, which can ...
Infrarednear fieldmicroscopyspectroscopysurfaceA short review of sub-wavelength microscopy in the mid-infrared range is given. The home built near-field optical microscope is described, which permits the aquisition of (i) an image with a sub-wavelength spatial resolution and (ii) an infrared ...
A novel approach to intrinsic Josephson-detection of far infrared radiation is reported utilizing near-zone field effects at electric contacts on c-axis oriented YBa 2 Cu 3 O 7-δ films. While only a bolometric signal was observed focusing the radiation far off the contacts on c-axis normal...
