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 ...

IBM has created low-loss (0.3% loss over 10 microns) silicon waveguide could enable new photonic chip designs for applications that rely on visible light, and could lead to more efficient lasers and ...

Silicon photonics is known as a key technology for modern optical communications at the near infrared wavelength-band, i.e., 1.31/1.55 μm. Currently silicon photonics has been desired to be extended ...

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 ...

As silicon photonics manufacturing gains momentum with additional foundry and 300mm offerings, process variation issues are coming to light. Variability in silicon processing affects the waveguide ...
