In this work, researchers use a sensitive camera to collect light from what's known as Rayleigh scattering, demonstrating the first in-situ measurements of light moving through an optical nanofiber.

Figure 1. Energy-level diagrams of Rayleigh scattering, Stokes Raman scattering, and anti-Stokes Raman scattering. The Raman Effect A ray of light is initially beamed onto a sample, which leads to ...

Researchers have developed a new technique for visualizing light propagation through an optical nanofiber. The result is a non-invasive measurement of the fiber size and shape and a real-time view of ...
