A random array of holes etched in a semiconductor structure, consisting of a periodic series of thin layers, has been demonstrated that emits mid-infrared laser radiation. The device could have ...

When we first heard the term “random laser,” we did a double-take. After all, most ordinary sources of light are random. One defining characteristic of a traditional laser is that it emits coherent ...

Like a pinball game in the hands of a good player, a collection of obstacles randomly positioned can be sufficient to trap light without the need for an optical cavity. By adding amplification, at no ...
