How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Conceptual depictions of wavenumber-selective nonlinear wavelength conversion in Kerr photonic crystal microresonators. Spatial modulation of the microresonator inner sidewall (pictured center) with a ...

A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for efficient hydrogen conversion, surpassing conventional photocatalysts. By ...

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 ...

Portland, Ore. — All natural materials bend electromagnetic radiation–from microwaves to visible light–in the same predictable direction: away from a line perpendicular to their surface, or away from ...
