Manipulating the topology of iso-frequency surface provides a new approach for control of light-matter interaction. This is demonstrated using anisotropic metamaterials consisting of metal-dielectric layers.

Metals have many disadvantages as components of optical metamaterials. Semiconductor-based materials overcome these problems. We build a high performance, all-semiconductor-based metamaterial by replacing metal with heavily-doped zinc oxide and demonstrate negative refraction in this near-infrared metamaterial. This demonstration
LCMRC researchers have developed a method for manipulating particles by light without touching them by using liquid crystals as a light-controlled host fluid.
Center researchers are collaborating with spin-off Displaytech (now part of Micron Technologies) to develop ferroelectric liquid crystal (FLC) materials for application in picoprojectors. The high-quality time sequential color and high brightness enabled by FLC switching speed, and high fill fact
In a photovoltaic cell, an incident photon creates an electron (black circle in top sketch) and a hole (open circle).
Ionic micellar assemblies have been simulated over μs time scales on GPUs (image on cover of Soft Matter).
