A New Way To Control Infrared Light

Material science and engineering enabling compact reprogrammable optical devices and circuits Associated Environmental Systems engineers and manufactures environmental chambers for material testing This 8-inch wafer contains phase-change pixels that can be controlled to modulate light. Researchers are studying the properties and behaviors of the pixels to inform the creation of future devices that use phase-change materials.

These materials are considered "phase-change materials and offer a dramatically enhanced "refractive index change" - this is induced by electrical field or temperature change.  "For instance — thereby enabling extremely compact reprogrammable optical devices and circuits."
