Driven to diffraction

As anyone with an interest in photography will know, to get features such as a powerful zoom, you usually need a big camera. The reason is that most cameras rely on refraction, whereby the light passing through lenses slows ...

Physicists propose method for braiding light

(Phys.org)—Physicists have proposed a way to braid three beams of light by guiding the beams along swirling, vortex-shaped defects in the optical medium through which the beams travel. The braided light would have an unusual ...

3D laser printing yields high quality micro-optics

Researchers have demonstrated 3D printing of micron-scale optics with unprecedented performance and reproducibility. Their approach can be used to create almost any type of integrated optical element on a micron or smaller ...
