Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next ...

Researchers at Tsinghua University developed the Optical Feature Extraction Engine (OFE2), an optical engine that processes data at 12.5 GHz using light rather than electricity. Its integrated ...

Abstract: The output coupler free external cavity spectral beam combining structure uses the beam along 0-order and 1-order diffraction direction as the feedback light beam to realize the wavelength ...

If only they were robotic! Instead, chatbots have developed a distinctive — and grating — voice. Credit...Illustration by Giacomo Gambineri Supported by By Sam Kriss In the quiet hum of our digital ...

Laser diffraction is recognized as the most reliable light scattering method for analyzing particle size distributions across a range from submicron to millimeter particles. The diffraction set-up ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

The toughest job a highbrow machinist can tackle is to make a diffraction grating. The end result does not look like much: just a piece of glass coated with a film of aluminum in which thousands of ...

Many of our viewers have noticed rainbow clouds over the past few days. This is actually a rare phenomenon called "cloud iridescence". This happens when sunlight is diffracted off of tiny water ...

Here’s the practical advice nobody gave me before I started my PhD. Twenty-five years ago, I packed my Jeep Wrangler and drove south for six hours to start a life-­defining journey: a doctoral program ...

Abstract: Cantilever-type sensors play a critical role in precision measurement across various fields. Among the available detection principles, the optical lever method detects minute cantilever ...
