  Ultrafast vibrational control of organohalide perovskite optoelectronic devices using vibrationally promoted electronic resonance

  Optically stimulated vibrational control for materials has the potential to improve the performance of optoelectronic devices. The vibrational control of FAPbBr₃ perovskite solar cells has been demonstrated, where the fast dynamics of coupling between cations and inorganic sublattice may suppress non-radiative recombinations in perovskites, leading to reduced voltage losses.

  Experimental realization of optical lumped nanocircuits at infrared wavelengths

  Lumped elements such as resistors, capacitors and inductors play a crucial role in electronic circuits. Now, inspired by metamaterials technology, the experimental realization of lumped circuit elements for optical frequencies provides a standardized platform for applications such as mixing and multiplexing of optical signals.

  Infrared-spectroscopic nanoimaging with a thermal source

  Fourier-transform infrared (FTIR) spectroscopy is a widely used spectroscopic technique, particularly for infrared wavelengths. However, for imaging applications the spatial resolution of FTIR spectrometers is restricted by the diffraction limit. The use of an FTIR spectrometer to pick up the low signal from scanning near-field optical microscopy employing thermal radiation now enables infrared imaging with nanoscale resolution.
