People love the rainbow of ROYGBIV colors: red, orange, yellow, green, blue, indigo and violet. Human eyes perceive visible light as this array of colors. You may notice that some colors you can ...

Cloaking devices and metamaterials are hot topics in the realm of science where optics blurs into materials science. By crafting materials that can interact with specific wavelengths of light, ...

Scientists have used a new lens to focus all the colors of the rainbow into one point. This is the first time a single lens has been used to focus the entire spectrum of light, including white light.

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

The Sun emits electromagnetic radiation across a broad spectrum, including visible, infrared, microwave, radio, ultraviolet, X-ray, and gamma-ray wavelengths. Visible light, comprising wavelengths ...

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