A solution-processed laser comprising PbS colloidal quantum dots integrated on a distributed feedback cavity, with tunable lasing wavelength from 1.55 μm to 1.65 μm.

Israeli and German researchers have developed a way to force an array of vertical cavity lasers to act together as a single laser – a highly effective laser network the...

A new method to produce a promising light source, usually available only in giant facilities, at a lab-scale tabletop.
