With enough computing effort most contemporary security systems will be broken. But a research team at the University of Sydney has made a major breakthrough in generating single photons (light particles), as carriers of quantum information in security systems.The collaboration involving physicists at the CUDOS, an ARC Centre of Excellence headquartered in the School of Physics, and electrical engineers from the School of Electrical and Informati...

The PHOTONICS CONGRESS CHINA will be held again in conjunction with LASER World of PHOTONICS CHINA at the Shanghai New International Expo Center from 15–17th March, 2016. The Congress topics will range from the latest research and development in laser technology, laser processing and its applications, laser additive manufacturing and laser 3D printing, manufacturing of optical components, machine vision, optoelectronics, advanced laser mate...

Perovskite solar cells show promise for cost-effective solar energy but heat stability is still an issue. This has been addressed by mixing perovskite materials with inorganic cesium to improve the solar cell’s thermal and structural stability. Using this approach, EPFL scientists have now developed a cesium-containing perovskite solar cell that has achieved efficiency of 21.1%, as well as record-level reproducibility.

Ophir Photonics Group at SPIE Photonics West 2016 announced the RM9-PD Radiometer, a sensor for measuring the power of very low level CW or quasi CW sources. The RM9-PD integrates a photodiode sensor and an 18Hz chopper into an easy-to-use system that measures very low powers.

Ophir Photonics has introduced its new M2 Beam Propagation software for the Pyrocam family of pyroelectric laser beam profiling cameras. Designed for measuring laser quality, the software incorporates M2 calculations that predict how a laser will focus and beam propagation parameters (BPP) that describe how the laser diverges as a function of the beam waist width.

A method of implementing an 'unbreakable' quantum cryptographic system is able to transmit information at rates more than ten times faster than previous attempts. Researchers have developed a new method to overcome one of the main issues in implementing a quantum cryptography system, raising the prospect of a useable 'unbreakable' method for sending sensitive information hidden inside particles of light.

World-leading nanoelectronics research center imec has announced the opening of its 300mm cleanroom. With this 4000m2 new facility, imec’s state-of-the-art semiconductor research cleanrooms now totals 12,000m2, one of the most advanced research facilities in the world dedicated to scaling IC technology beyond 7nm.

Carolin Fischer has been appointed Exhibition Director for LOPEC, the International Exhibition and Conference for the Printed Electronics Industry. She replaces Anja Schneider, who has taken up a new post as Exhibition Director for AUTOMATICA, the trade fair for industrial automation.

Ophir Photonics Group at SPIE Photonics West 2016 announced StarViewer, an Android app that brings laser power/energy measurements to Android smartphones and tablets. StarViewer can be used with virtually any Ophir thermopile, photodiode, or pyroelectric PE-C laser sensor. Data can be displayed in a variety of formats: time-based line graph, needle display, or large numeric display with statistics.

A group of researchers from the UK, including academics from Cardiff University, has demonstrated the first practical laser that has been grown directly on a silicon substrate. It is believed the breakthrough could lead to ultra-fast communication between computer chips and electronic systems and therefore transform a wide variety of sectors, from communications and healthcare to energy generation.
