Astronomy on a chip

Professor Dr Martin Roth, at research centre Innofspec Potsdam, discusses the role that fibre Bragg gratings and other photonics components could play in transforming astronomy

Driving Moore’s law with CO2 lasers

Matthew Dale reports from the European Photonic Industry Consortium’s Executive Meeting on Industrial Lasers, where it was explained how CO­2 lasers could be used to produce the next generation of computer processors

Taking the heat off PICs

Shrinking optoelectronic components and combining them with silicon devices requires careful consideration of thermal management, finds Andy Extance

Scaling spectroscopy

Matthew Dale discovers how scaling spectrometers down to the chip level enables them to be mass-produced in standard MEMS foundries, making spectroscopy more affordable for various new applications
