In their proof - of - principle experiment, the researchers used germanium antimony telluride (GST)-- the kind of phase - change material found in CDs and DVDs — to make an improved switchable metasurface that can block or transmit particular wavelengths of light at the command of light pulses.

«Permanent data storage with light: Researchers develop the first non-volatile all - optical chip memory based on phase change materials.»

The amplitude and phase of the laser beams can be changed during each run of the experiment, with the result that either the detector or the eye can detect the light pulse, and sometimes both simultaneously or neither at all.

The phase - change materials can manipulate light - by electrical, optical or mechanical means - they can be used to filter, steer or dim light using very little power.

At that time, there were major advances in Building Sector technologies — in glazing materials (heat mirror and low - e coatings), passive and active solar energy systems design and applications, passive and active cooling applications, natural ventilation systems, phase - change materials, moveable insulation, building simulation modeling programs, daylighting systems and controls, energy management systems, night set - back thermostats and occupancy sensors, solar hot water heating, solar thermal electric generation and storage, photovoltaics and advances in low - energy lighting systems, to name just a few.
