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, ...

The Fraunhofer Institute for Photonic Microsystems (IPMS), Dresden, Germany, has previously presented a mobile MEMS scanning grating spectrometer in "sugar cube" format at Photonics West; the ...

Diffraction gratings are important optical components and are used in many areas of optics such as in spectroscopy. A diffraction grating is a periodic structure that splits and diffracts the ...

The scanning interference field exposure technique is an effective method to fabricate holographic diffraction grating with meter-level size and nano-level precision. The main problems of fabricating ...
