Light Sources for New Quantum Technology

Light Sources for New Quantum Technology

Electronic circuits are based on electrons, but one of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons. First, it is necessary to be able to create a stream of single photons and control their direction. Researchers around the world have made all sorts [...]

Beyond Silicon: Next Generation Electronic Device

Beyond Silicon: Next Generation Electronic Device

In the consumer electronics industry, the mantra for innovation is higher device performance/less power. Arun Thathachary, a Ph.D. student in Penn State’s Electrical Engineering Department, spends his days and sometimes nights in the cleanroom of the Materials Research Institute’s Nanofabrication Laboratory trying to make innovative transistor devices out of materials other than the standard semiconductor [...]

Laser-Like Light Emission: Optical Resonators

Laser-Like Light Emission: Optical Resonators

By combining plasmonics and optical microresonators, researchers at the University of Illinois at Urbana-Champaign have created a new optical amplifier (or laser) design, paving the way for power-on-a-chip applications.   “We have made optical systems at the microscopic scale that amplify light and produce ultra-narrowband spectral output,” explained J. Gary Eden, a professor of electrical [...]

Laser Pulse Turns Glass Into a Metal

Laser Pulse Turns Glass Into a Metal

For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. This has been shown by calculations at the Vienna University of Technology. The effect could be used to build logical switches which are much faster than today’s microelectronics. Quartz glass does not conduct electric [...]

New Tool Makes a Single Picture Worth a Thousand – and more – Images

New Tool Makes a Single Picture Worth a Thousand – and more – Images

A photo is worth a thousand words, but what if the image could also represent thousands of other images?   New software developed by UC Berkeley computer scientists seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can [...]
