Using photons to create more powerful and power-efficient processing units for artificial intelligence. Machine learning performed by neural networks is a popular approach to developing artificial intelligence, as researchers aim to replicate brain functionalities for a variety of applications.

A paper in the journal Applied Physics Reviews, by AIP Publishing, proposes a new approach to perform computations required by a neural network, using light instead of electricity...

Researchers at Tokyo Institute of Technology (Tokyo Tech) have designed a 28 GHz transceiver that integrates beamforming with dual-polarized multiple-input and multiple-output, MIMO technology. Measuring just 3 mm by 4 mm, this tiny transceiver could help improve performances of fifth-generation cellular network (5G) and Internet of Things (IoT) devices.

A team of researchers led by Kenichi Okada at Tokyo Tech’s Department of Electrical and Electronic Engineering has devised a strategy with a clear eye on supporting high-speed mobile data access using the millimeter-wave spectrum for 5G, the highly-anticipated wireless network o...

Researchers have developed the world’s most narrowband diode laser on a chip. This laser represents a breakthrough in the fast-growing field of photonics, and will bring applications like 5G internet and accurate GPS closer. We are slowly reaching the bounds of what is possible with electronics. That is why scientists and the private sector are committed to photonics – a key technology that makes numerous other innovations possible. This involves the deployment of photons (light particles) for transporting and processing data.

For photonic chips to function as efficiently as possible, one has to be able to properly control the light signals...

Fabricated in interlocking segments like a 3-D puzzle, the new integrated circuits could be used in wearable electronics that adhere to the skin like temporary tattoos. Because the circuits increase wireless speed, these systems could allow health care staff to monitor patients remotely, without the use of cables and cords.
