For decades, laser engineers have wrestled with an embarrassing blind spot: the green-through-yellow slice of the visible ...

In a potential breakthrough in the field of photonics, a team of researchers reports they have successfully manipulated light at the sub-wavelength scale. Previously thought to be impossible, the ...

EPFL researchers have come up with a new approach to electronics that involves engineering metastructures at the sub-wavelength scale. It could launch the next generation of ultra-fast devices for ...

Fiber lasers use an optical fiber doped with rare-earth elements (erbium, ytterbium, neodymium, etc.) as their optical gain source. They emit high-quality beams, they are efficient and durable, and ...

A new technical paper titled “Integrated phononic waveguide on thin-film lithium niobate on diamond” was published by researchers at Stanford University and UC Santa Barbara. “We demonstrate ...
