Using thin films of dielectric materials in optical coatings have long been common practice in the glass and optics industries. For example, Bragg mirrors in laser cavities are formed using ...

Welcome to science world! Today, we're going to have a look at a particular type of wave - a light wave. Who knew so many different things travelled in waves? A light wave travels faster than anything ...

Silvery fish have evolved an elegant optical scheme for overcoming the Brewster effect, creating broadband, polarization-neutral reflections for any angle of incidence. Nicholas Roberts explained to ...
