Greg Blackman speaks to Mario Krenn at the University of Vienna on work sending light-encoded images 3km through the air across the city`s skies

Greg Blackman looks at the optics for ultrashort pulsed lasers, including those planned for the Extreme Light Infrastructure Beamlines facility, expected to become operational at the end of 2017

In order to reach higher powers, diode laser companies are employing various cooling techniques within their diode stacks. Tom Eddershaw investigates the technology

Jessica Rowbury looks at the variety of uses for photonics technologies in cosmetics, and discovers how the industry is addressing safety

Dr Andrew Fearnside, a senior associate at law firm Appleyard Lees, sets out the arguments for protecting intellectual property when commercialising photonics innovations, and what to consider when seeking IP protection

The United Nations has proclaimed 2015 the International Year of Light (IYL) and Light-based Technologies, a chance to engage the public and promote photonics all over the world. Jorge Rivero Gonzalez, the European Physical Society`s IYL 2015 outreach officer, discusses the opportunities the initiative offers
