New nanomechanical oscillators with record-low loss

The vibrational modes of nanomechanical resonators are analogous to different notes of a guitar string and have similar properties such as frequency (pitch) and lifetime. The lifetime is characterized by the quality factor, ...

Tiny chip provides a big boost in precision optics

By merging two or more sources of light, interferometers create interference patterns that can provide remarkably detailed information about everything they illuminate, from a tiny flaw on a mirror, to the dispersion of pollutants ...

Research produces intense light beams with quantum correlations

The properties of quantum states of light are already leveraged by such highly sophisticated leading-edge technologies as those of the latest sensitivity upgrades to LIGO, the Laser Interferometer Gravitational-Wave Observatory, ...

Laser prototype for space-based gravitational wave detector

Researchers have announced a prototype for a laser at the heart of the first space-based gravitational wave observatory, known as the Laser Interferometer Space Antenna (LISA) mission. The team's new laser nearly meets the ...

The economic impact of a Very Large Telescope

The European Southern Observatory's VLT, Very Large Telescope, is a group of four 8.2-metre diameter optical telescopes located in northern Chile. It also has four movable 1.8-metre diameter auxiliary telescopes and they ...

Scaling up breakthrough optical fibre micro sensors for market

Scientist Davide Iannuzzi and his team have developed a method to place novel miniaturised mechanical devices on the tips of optical fibres. The technology has many applications, such as providing a new generation of small, ...
