A rendering of the metasurface chip in action. When hit with an infrared laser, the microscopic chip converts the incoming light to a higher frequency and sends it out as a narrow beam that can be ...

As humans spend increasing amounts of time indoors, we lose access to the sun’s natural benefits. Recognition of season affective disorder has grown accordingly. While the actual occurrence of the ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...

The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the development of advanced technologies. Researchers at the Advanced Science ...
