As the device is irradiated by light, the pyroelectric potential produced by light induction modulates the built-in electric field at the device contact interface, which will change the carrier transport process. The built-in electric field and pyroelectric potential formed when different types of ...
“We have been working on materials that can change the direction of oscillation of light for some time now,” said Pimenov. The research was published in Nature Communications (doi:10.1038/ncomms15197). There are 448 suppliers of Optics in the Photonics Marketplace.Published...
In order to address this shortcoming, another immobilization approach was considered, which would allow decreasing the distance of the binding target to the sensor surface. It is based on a MUA self-assembled monolayer, binding on one side via thiol to the gold, and providing the means for an...
Importantly, the two-level dressed-atom model predicts that for increasing photon energies, the OSE energy-shift will change signs from a blue-shift forhυ < EAto a red-shift forhυ > EA. Experimentally, as is shown in Fig.1c, we instead observe that the blue-shift persists ...
30 kHz and are wavelength insensitive; but they are binary amplitude SLMs and therefore phase modulation requires encoding techniques [4]. Newer devices with higher resolution, higher speed, or extended operational spectral ranges have led to progress in many different areas of optics & photonics...
papers, published in a short window before the prize," Azoulay says. Moreover, he adds, the greatest gains come for papers in new areas of research, and for papers published in lower-profile journals. Younger researchers who had lower profiles previously were more likely to see a change as...
Another goal was to address several instances where the current Wassenaar controls were ambiguous or outdated, such as fiber lasers. Fiber lasers did not exist when the COCOM controls were created, and their status under the previous Wassenaar controls was unclear. Another ambiguous issue was nonlin...
To address these issues, the researchers used an instrument that allowed them to identify changes in the relative costs of offshore activity resulting from new bilateral tax treaties. These treaties allow U.S. firms to avoid double taxation, lowering the average effective tax rate and the overall...
