Quantum dot laser paves the way for lower-cost photonics

140304130031 large

With the explosive growth of bandwidth demand in telecommunications networks, experts are continually seeking new ways to transmit increasingly large amounts of data in the quickest and cheapest ways possible. Photonic devices — which convert light to electricity and vice versa — offer an energy-efficient alternative to traditional copper network links for information transmission. Unfortunately, these devices are also almost always prohibitively pricey.

It is uncommon that a company founded only few years ago suddenly becomes widely known not only in the country it was based in, but also in the international arena. This story happened with a high-tech company Brolis Semiconductors founded in 2011, and currently it is well-known not only in Lithuania, but also globally – from Japan to USA. The company specializes in designing semiconductor lasers, laser diodes, and other products. What makes these lasers special? Continue reading “Three Brothers – One Story of Luck (1)” »

Petawatt ‘Death Star’ laser prepares to investigate quantum mechanics, chemistry, and more

As high-power lasers have become increasingly important in scientific research, engineers have been working to build more powerful beam emitters. Now Lawrence Livermore National Laboratory (LLNL) in California is taking it to the extreme with a new laser project. If the High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) lives up to its promise, it will be able to produce a laser with over 1 petawatt of power in extremely fast pulses.

A New Way to Trap Light: Phenomenon Could Lead to New Types of Lasers and Sensors

130710141854
There are several ways to "trap" a beam of light -- usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that could find a wide variety of applications.
