Diamond as a building material for optical circuits

The application of light for information processing opens up a multitude of possibilities. However, to be able to adequately use photons in circuits and sensors, materials need to have particular optical and mechanical properties. ...

Low-noise, chip-based optical wavelength converter demonstrated

(Phys.org)—Researchers from the NIST Center for Nanoscale Science and Technology have demonstrated a low-noise device for changing the wavelength of light using nanofabricated waveguides created on a silicon-based platform ...

New etching method helps to build 3-D structures from 2-D template

In modern telecommunications, light carries digital information over kilometers within seconds. Adapted optical materials control the light signals. In the Advanced Functional Materials journal, researchers from Berlin, Louvain, ...

New study gives insight into graphene grain boundaries

(Phys.org)—Using graphene – either as an alternative to, or most likely as a complementary material with – silicon, offers the promise of much faster future electronics, along with several other advantages over the ...

Robot hands gain a gentler touch

(Phys.org) —What use is a hand without nerves, that can't tell what it's holding? A hand that lifts a can of soda to your lips, but inadvertently tips or crushes it in the process?

Microfabrication methods to help navigate a day without GPS

Military missions of all types need extremely accurate navigation techniques to keep people and equipment on target. That is why the Military relies on GPS or, when GPS is unavailable, precise sensors for navigation. These ...
