Breaking the diffraction limit for the resolution of conventional optical systems has long ... object are present in so-called scattered evanescent waves, these waves decay exponentially with ...

By removing the cladding in a small section of the fiber, the evanescent wave is exposed to the environment. As light travels through the optical fiber, the evanescent wave interacts with gold ...

Here we demonstrate a low-profile and cavity-free size spectrometer for probing fine and ultrafine particulate matter by using the enhanced particle-perturbed scattering in strong optical ...

Researchers from the Indian Institute of Technology Guwahati created a new optical sensor that offers a straightforward ...
