Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the
From the minuscule bindings of molecules to the far reaches of space, we’re exploring the universe around us by catching sight of the smallest particles of
This project aims to develop rigorous measurements and methodology needed for determining optical and electrical properties of advanced materials that might be
ROSI (Robotic Optical Scattering Instrument) is a new facility for measuring reflectance and scattering of materials in the ultraviolet to short-wave infrared
We study how material properties, surface topography, and contaminants affect the distribution of light scattered from surfaces. Our aim is to support industry
We synthesize semiconductor nanostructures to serve both as test structures for measurement techniques and as building blocks for novel metrology tools and
