A direct UV writing technique that can create multiple Bragg gratings and waveguides in a planar silica-on-silicon chip is enabling sensing applications ranging from individual disposable sensors for ...

Stratophase, a spin-off from Southampton University in the UK, has developed a technique to simultaneously write a waveguide and a planar Bragg grating into an optical silicon chip. The technology has ...

Corning has become the latest blue-chip firm to invest in DigiLens, the Silicon Valley company developing holographic waveguides based on Bragg gratings. NYSE-listed Corning, ranked high among the ...

For decades, the speed of our computers has been growing at a steady pace. The processor of the first IBM PC released 40 years ago, operated at a rate of roughly 5 million clock cycles per second ...

Researchers have succeeded in making the thinnest ever optical device in the form of a waveguide just three atomic layers thick. The device could lead to the development of higher density ...
