Physicists propose method for braiding light

(—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 ...

Fabricating 3D Photonic Crystals

( -- “In photonic crystals, the ability to control the structure of a material in full three dimensional space, allows you to control the way that light flows through it,” John Rogers tells “This ...

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 ...
