In 2000, Sandia used a 416-nanometer cheesecloth-like crystal to bend infrared light with little loss. 26 years later, the approach still guides research into faster, cooler photonic chips

Sandia researchers developed a tiny structure guiding infrared light with minimal loss. This artificial crystal, made from gallium arsenide, controlled light wavelengths effectively. The design offered potential for more efficient lasers and faster photonic chips. Researchers used cladding and nanoscale holes to keep light confined within the structure.
