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 ...
