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 ...

This article is focused on the correct procedure to be followed to determine the value of responsivity while calibrating white LED lights on the Metrohm Autolab Optical Bench. This has three types of ...

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

Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When ...

Question: How could I measure the light intensity of different light sources? Answer: Take a red, green, blue LED. Determination of the light intensity can be crucial, for example, if you want to ...

Silicon-based device “like a nanoscale optical parametric oscillator” could enable variety of photonic applications. Silicon-based device may enable variety of photonic applications. Researchers have ...

It's not easy being green. Scientists for years have made small red and blue lasers, but other colors, including green, have been a challenge. A team has now filled this technology gap by creating ...

Photons are odd little beasts. They can act like waves. They can act like particles. They are teeny tiny messengers of force. They are carriers of energy. If you're enjoying this article, consider ...
