Fiber optic SERS probes, called “optrodes,” combine spectroscopy with the flexibility and versatility of fiber optic cables.

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

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 ...

Periodic signal analysis enhances optics and photonics experiments using lock-in amplifiers and boxcar techniques.

Lighting and display manufacturers must ensure their products are consistent in their light output, making them reliant on effective quality control methods. Their products must be validated, and ...

A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Technical University of Vienna (TU Wien) could ...
