An ark-shaped diffraction grating is used to selectively reflect light from a laser back into the device. The photo also shows the waveguides used to channel light ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

Optical microelectromechanical systems (MEMS) devices are driving the trend toward all-optical telecommunication networks. With the ability to directly manipulate an optical signal, MEMS have several ...

Editor's Note: To view a PDF version of the article, Click Here. The commercial introduction of wafer-based, nanofabrication techniques now makes it possible to create a new class of optical ...

ZEISS has a long tradition in the design and manufacture of optical diffraction gratings for OEM spectroscopic instruments and laser applications. For the last 75 years ZEISS has developed ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new ...

Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating. A diffraction grating is a kind of optical component whose ...

As stated in the article titled ‘An Introduction to a Spectrometer: The Slit’, a spectrometer is an imaging system that maps a plurality of monochromatic images of the entrance slit onto the detector ...
