Routing optics are used to route the light within the spectrometer, from the entrance slit to the diffraction grating and on to the exit slit and detector. Filters are used in spectrometers that have ...

Yongqiang Wei at the A*STAR Data Storage Institute and co-workers have now fabricated a silicon chip that integrates not only a laser, but also an optical grating that provides optical gain and ...

When an infrared laser was beamed through this grating, the light was deflected with an efficiency of over 50%. Higher efficiencies should be possible with further work, the team says.

It’s not often we see candy optics, but we like it — and if you fail, you can always eat your mistakes and try again. If you’re wondering what you can do with a diffraction grating, check ...

Another benefit of holographic gratings is that they are easily formed on concave surfaces, allowing them to operate as both the focusing optic and the dispersive element simultaneously. The amount of ...

A fiber Bragg grating is an optical element inscribed ... In The Optical Society (OSA) journal Optics Letters, the researchers show that gratings etched into the bioresorbable glass fiber dissolve ...

“In addition, more advanced optical elements could be realised,” Schrödel continues. “This could enable exciting new directions for ultrafast optics, and other fields which face limits in optical ...
