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 ...

The goal of using standard silicon-IC technology to create smaller, better, and possibly less-expensive yet highly sophisticated instrumentation is extending to the optical domain. There’s major ...

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 ...

Near infrared optical coherence tomography (NIR OCT) is a non-contact, noninvasive imaging technique that uses near infrared light to generate cross-sectional images from the light scattered back by a ...

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 ...

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