Laser diodes are convenient light sources, but for precise optical work their often-elliptical beam profile leaves something to be desired. One way to get around this is to couple the beam into a ...

Last month we discussed how all interconnects will be optical in the data center in five years, but that’s only part of the story. Every optical interconnect needs a laser. The laser provides the ...

Forward-looking: Columbia University researchers have developed a compact photonics chip capable of producing dozens of laser wavelengths from a single high-power source, a breakthrough that could ...

Researchers developed a new optimized printing approach that could enable super-resolution 3D direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and ...

Scientists at NPL have demonstrated the best-reported laser frequency stability achieved with an optical reference cavity operating at room temperature, marking a major advance in ultrastable laser ...
