Guiding the random laser

At its most basic level, a random laser is precisely what its name implies; random. It's random in the spectrum of light it produces and in the way that light is emitted, making what could be an extremely versatile laser ...

Capturing an elusive spectrum of light

Researchers led by EPFL have built ultra-high quality optical cavities for the elusive mid-infrared spectral region, paving the way for new chemical and biological sensors, as well as promising technologies.

Transforming living cells into tiny lasers

In the last few decades, lasers have become an important part of our lives, with applications ranging from laser pointers and CD players to medical and research uses. Lasers typically have a very well-defined direction of ...

A prison for photons in a diamond-like photonic crystal

Scientists from the MESA+ Institute for Nanotechnology at the University of Twente in the Netherlands have designed a novel type of reso­nant cavity that serves as a prison for photons. The cavity confines light in all three ...

A low-energy optical circuit for a new era of technology

Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists at Ecole Polytechnique Federale de Lausanne have developed a first building-block for photonic ...

Scientists develop new hybrid energy transfer system

Scientists from the University of Southampton, in collaboration with the Universities of Sheffield and Crete, have developed a new hybrid energy transfer system, which mimics the processes responsible for photosynthesis.
