Light collection efficiency is an important factor that affects the performance of many optical and optoelectronic devices. In these devices, the high reflectivity of interfaces can hinder efficient ...

To investigate the influence of gravity on the propagation of light, researchers usually have to examine astronomical length scales and huge masses. However, physicists have shown that there is ...

Fran: I am looking at my reflection. When light from an object is reflected by a surface, it changes direction - it bounces off the surface. So, if we shine this light onto this mirror, then we can ...

(Nanowerk News) Transparent plastic optical lenses can be manufactured cheaply and in any shape. However, a downside is that they reflect light just as much as glass does. At the K trade fair in ...

LIGHT, which in everyday experience travels in straight beams, has been trapped on complex curved surfaces. The feat is not just a parlour trick – it could help people visualise how light travels in ...
