Fujitsu of Japan has created a new venture company called QD Laser to bring commercial quantum-dot lasers and amplifiers to the market as rapidly as possible. Adarsh Sandhu spoke to its chief executive officer about the firm's plans.

The idea behind quantum-dot lasers has been around for a long time, but only recently has the field made headway in developing robust commercial products. Nadya Anscombe spoke to German firm Innolume to find out why they believe the technology will take off.

In today's era of start-ups, spin-offs and university–industry collaborations, it pays to be knowledgeable about patents and how they can help.

Laser pioneer, Theodore Maiman died on Saturday 5 May 2007, aged 79. His legacy lives on.

Experiments now show that the force exerted by light can be used to pull a waveguide towards a microdisk resonator, illustrating how optical forces could be used for positioning and control in integrated microphotonics.

Attosecond science and quantum-cascade lasers are topics that were both garnering great attention at this year's CLEO/QELS conference.

The development of monolithic arrays of high-power, single-mode semiconductor lasers is set to bring big benefits to the printing, coding and marking industries.

Terahertz sources are already hitting the market as parts of imaging systems. Nature Photonics spoke to Carlo Sirtori from the University of Paris-Diderot and Thales Research and Technology about the implications of merging terahertz and telecommunication technologies.

Creating a start-up company can be a very rewarding and lucrative experience, but it is important not to underestimate the difficulty of the task.

A growing number of enterprises around the world are now commercializing fibre Bragg grating sensors for sensing everything from temperature and pressure to vibration and strain. Duncan Graham-Rowe reports.

Nanophotonics has emerged as an exciting new arena concerned with the interaction of light with nanostructured materials. But if nanophotonics is to maximize its impact on the market and the next generation of technology, those within the field will need to form a cohesive plan.

The combination of superconducting single-photon detectors and phase-shift keying technology has enabled a leap in the performance of quantum cryptography.
