1. Opto Diode Announces AXUV300C, A Large, Rectangular Photodiode For Electron Detection 3/25/2020

   Opto Diode Corporation, an ITW company, introduces the AXUV300C photodiode with a large 331 mm² rectangular active area. The new device is part of Opto Diode’s AXUV detector family that features high-performance detection of photons, electrons, and radiation.

2. Powerful Emitters With Short Rise Times: VCSELs For Greater Range And Higher Resolution In LiDAR Applications 3/24/2020

   LASER COMPONENTS has expanded its range of VCSEL lasers. Its wide range of products now includes emitters with 850 nm and 940 nm in power classes between 200 mW and 50 W. All products are characterized by extremely short rise times and thus support pulse trains in the low nanosecond range and below. Thanks to the semiconductor structure, the emission wavelength remains nearly constant, even with temperature fluctuations. This allows narrow-band bandpass filters to be used on the detector side. Upon customer request, the laser diodes are also available as powerful arrays.

3. Advanced ‘Super-Planckian’ Material Exhibits LED-Like Light When Heated 3/23/2020

   Could there be a new kind of light in the universe? Since the late 19th century, scientists have understood that, when heated, all materials emit light in a predictable spectrum of wavelengths. Research published today in Nature Scientific Reports presents a material that emits light when heated that appears to exceed the limits set by that natural law.

4. On The Trail Of Organic Solar Cells’ Efficiency 3/20/2020

   Scientists at TU Dresden and Hasselt University in Belgium investigated the physical causes that limit the efficiency of novel solar cells based on organic molecular materials. Currently, the voltage of such cells is still too low - one reason for their still relatively low efficiencies.

5. Tiny Double Accelerator Recycles EnergyTiny Double Accelerator Recycles Energy 3/20/2020

   A team of DESY scientists has built a miniature double particle accelerator that can recycle some of the laser energy fed into the system to boost the energy of the accelerated electrons a second time.

6. High-Speed Microscope Captures Fleeting Brain Signals 3/19/2020

   Electrical and chemical signals flash through our brains constantly as we move through the world, but it would take a high-speed camera and a window into the brain to capture their fleeting paths.

7. Innovative New Fabrication Approach For Reprogrammable Photonic Circuits 3/19/2020

   Modern society relies on technologies with electronic integrated circuits (IC) at their heart, but these may prove to be less suitable in future applications such as quantum computing and environmental sensing.

8. Compact Beam Steering Research To Revolutionize Autonomous Navigation, AR, Neuroscience 3/19/2020

   While beam steering systems have been used for many years for applications such as imaging, display, and optical trapping, they require bulky mechanical mirrors and are overly sensitive to vibrations.

9. Scientists From ITMO University Describe And Emulate New Quantum State Of Entangled Photons 3/19/2020

   A research team from ITMO University, with the help of their colleagues from Moscow Institute of Physics and Technology and Politecnico di Torino, has predicted a novel type of topological quantum state of two photons and proved their predictions experimentally.

10. Army Scientists Create Innovative Quantum Sensor 3/19/2020

    A quantum sensor could give Soldiers a way to detect communication signals over the entire radio frequency spectrum, from 0 to 100 GHz, said researchers from the Army.
