ANALYSIS

Far-reaching photonics Photonics permeates almost every sphere of science and society. International Innovation highlights some of the broad applications of photonics technology

THE POWER OF LIGHT: defining photonics Photonics is the technology of using, producing or modifying light. This includes light emission, transmission, deflection, amplification and detection by lasers and other light sources, optical components and instruments, fibre optics, electrooptical instrumentation, related hardware and electronics, and sophisticated systems.

AGRICULTURE

PHOTOVOLTAIC

Photonics can accelerate or slow down the growth of tomatoes depending on market demand

The wavelength of light can be tuned to modify the taste of vegetables

RESEARCH

COMMUNICATION

Specially shaped, high purity glass in telescopes can enable us to look into Space at distances up to 50 billion light years

104 INTERNATIONAL INNOVATION

Photonics uses photons – the fundamental particles of light – in the same way that electricity uses electrons and is likely to be as important for technological development in the 21st Century as electricity was in the 20th Century. The range of photonics applications extends from energy generation to communications and information processing.

Photonics can be used to transmit data through fibre optics, providing super-fast internet access

Photovoltaic film coating ordinary windows can convert them into solar panels

Camels with solar-panelling can carry medicines across the desert while keeping it refrigerated

INDUSTRY AND MANUFACTURING

A laser can cut many materials very precisely including metal, plastic, textile and paper. This technology is used in many industrial activities from car manufacturing to producing small components for luxury watches

3D printing can add layers of melted material to create any shape. A laser melts and deposit metal or harden powder. It is very useful for prototyping in industry
