How can we capture ultrafast optical signals in real time? A time lens is one possibility — able to image the temporal profile of a short optical signal, analogous to a conventional lens.

The final single color lens is developed on a plate and resembles silicon chips before they’re put into larger circuits. Paper-thin optical lenses simple enough to mass produce like microchips ...

FZPs have become a good candidate to improve optical devices where space is critical. And for the first time, researchers crafted sample lenses with just a few straightforward steps using industry ...

An optical fiber is constructed of a transparent core made of nearly pure silicon dioxide (SiO2), through which the light travels. The core is surrounded by a cladding layer that reflects light ...
