New research has achieved a significant breakthrough in color switching for nanocrystals, unlocking exciting possibilities for a simple, energy efficient display design and for tunable light sources ...

A new ring-based tunable laser on a chip emits multiple wavelengths smoothly, offering a compact, cost-effective alternative for sensing, diagnostics, and more. (Nanowerk News) Researchers in the ...

Berkeley -- Today's transistors and light emitting diodes (LED) are based on silicon and gallium arsenide semiconductors, which have fixed electronic and optical properties. Now, University of ...

A team at Harvard and Technical University of Vienna have invented a new tunable laser that uses a series of rings to smoothly emit many light wavelengths from a single chip. The laser could replace ...

If you need bright blue light at a very specific wavelength, the National Institute of Standards and Technology (NIST) can make it—and fast. NIST has developed a “rainbow source” that can be tuned ...
