An optical spectrometer is an instrument used to measure properties of light over a specific portion of the light spectrum. These devices have found a wide range of practical applications. Dispersive ...

Polaritons are coupled excitations of electromagnetic waves with either charged particles or vibrations in the atomic lattice of a given material. They are widely used in nanophotonics because of ...

Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers ...

Researchers present the integration of a detector system and a polaritonic platform in the same 2D material, enabling for the first time the detection of 2D polaritonic nanoresonators with spectral ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...
