Two researchers have taken a different approach to large-mode-area fiber design by changing the gain-guided and index-antiguided fiber design, which is conventionally step-index...

Label-free optical spectroscopy may enable operational insight into Alzheimer's disease and perhaps even early diagnosis so that patients can make decisions while still cognitively...

A team of researchers has fabricated "in-chip" microstructures and photonic devices deep within silicon using nonlinear laser lithography that enable dense, truly 3D silicon photonics...

Brightly colored research greenhouses equipped with electricity-producing luminescent solar concentrators take light only from the spectral regions that are less needed by the...

A biosensor that uses polydimethylsiloxane (PDMS) dye-doped optical fibers is more thermally and environmentally stable than when using hydrogel fibers.

The design contains a laser-plasma wakefield accelerator to produce a high-quality relativistic electron beam, and a terahertz light source capable of producing a single-cycle...

A new multiphoton excitation technique allows on-demand optogenetic photostimulation of custom neuron ensembles.

Researchers at the Free-Electron Laser in Hamburg have come up with a bolometric radiometer that is only 26 mm on a side, enabling easy measurement of a free-electron laser beam...

Although digital marketers can be accused of transforming "listicles" -- web articles in the form of lists -- into a simplistic tool for generating clicks, Laser Focus World has...

The week of October 16, 2017 was Photonics Week in Berlin, and the local photonics community convened in Adlershof. The meeting attracted around 500 people. Not much for a big...

As laser materials processing applications become more challenging, digital servos must steer laser beams with higher precision, flexibility, and finesse than their analog predecessors...
