Nano-Structured Optics and Optical Surface Metrology

Aspheric, free-form, and nano-structured surfaces are indispensable in high-performance optical systems. The ability to accurately manufacture … more

Molecular Imaging

Biophotonics is at the intersection of photonics and biology where light is used to image, detect, and manipulate biological materials. This … more

Frequency Conversion Interfaces for Photonic Quantum Systems

Optical frequency conversion, in which the color of light is changed, is a process that has numerous applications in physics and technology.  For … more

Nanoplasmonics and Three-Dimensional Plasmonic Metamaterials

Metamaterials are tailor-made photonic composites--combinations of materials designed to achieve optical properties not seen in nature. The … more

Optical scattering from surfaces

We study how material properties, surface topography, and contaminants affect the distribution of light scattered from surfaces. Our aim is to … more

Optical grating scatterometry

This program aims to develop standards, methods, and modeling for assessing the periodic structures using optical reflectance and transmittance … more


SCATMECH is an object-oriented C++ class library developed to distribute models for light scattering applications. Included in the library are … more

Electron holography

An electron hologram is a fringe modulated image containing the amplitude and phase information of an electron transparent object. The HolograFREE … more
