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 have developed a first building-block for photonic 'transistors' that requires record-low energy to operate. The device is a big step forward in the development and implementation of optical circuits.
