Metasurfaces offer an innovative approach to controlling light. Courtesy: P Genevet Vertical-cavity surface-emitting lasers (VCSELs) have emerged as a highly versatile light source over the past 30 ...

On a late night in February 2011, two Princeton University researchers packed a small object into a box and set it out for the morning mail. The engineers had spent four years developing a new type of ...

Aspheric lenses are designed to focus or collimate light without introducing spherical aberration into the transmitted wavefront. For monochromatic sources, spherical aberration is often what prevents ...

The optical industry “almost completely relies on mechanical processes in its process chains,” So says laser and photonics research center Fraunhofer Institute for Laser Technology (ILT). This, ...
