An Electron Caught in the Act

How fast is an electron? Australian scientists were able to measure it. Australia's fastest camera, located at the Attosecond Science Facility, has revealed the time it takes for molecules to break apart. The experimental research, conducted by Griffith University's Centre for Quantum Dynamics, aims to help in the...

Optical Monitoring System Enables Greater Accuracy In Thin-Film Coatings

The challenges in achieving greater accuracy in optical thin-film coatings, both historically and in today's coating processes, are many and deserve our scrutiny. The “old” way of designing and manufacturing coatings was to use a thin-film design software like TFCalc,...

2.2-Micron, Uncooled, InGaAs Photodiodes and Balanced Photoreceivers up to 25-GHz Bandwidth

Traditional applications for 2-micron photodetectors have been largely dominated by passive remote sensing where detectors having bandwidth of even one megahertz are deemed sufficient. The onus in such applications is to achieve low dark current through...

Fiber-Optic Environmental Radiation Dosimeter

An all-optical, fiber-optic-coupled remote radiation sensor was developed using luminescent, copper-doped quartz material. The key to the technology is the doped quartz material, which produces a luminescence signal that is directly proportional to the radiation dose.
