IF you’ve ever spotted the little silica gel packets that come inside new handbags or with new shoes don’t chuck them away.

A trio of astronomers from the University of Tokyo and Niigata University have found what they describe as "peculiar embedded icy objects" thousands of light years from Earth. Takashi Shimonishi ...

Scientists have developed a compact optical amplifier based on a photonic chip that vastly outperforms traditional optical amplifiers in both bandwidth and efficiency. This breakthrough could reshape ...

Australia’s only silicon manufacturer has been awarded funding from the Albanese Labor government, to help decarbonise its operations.

They begin by covering a silicon wafer with a layer of silicon dioxide and etching in arrowhead-shaped trenches (“like a field plowed prior to planting” as IEEE Spectrum describes it).

Using gallium phosphide-on-silicon dioxide technology, thecompact photonic chip boosts signals with unprecedented efficiency.

Smarter, Faster, and More Efficient Signal Boosting A new optical amplifier is changing the game. Unlike conventional ...

The trick was to accept the lattice mismatch and instead focus on confining the resulting flaws through a layer of silicon dioxide on top of the wafer. In this layer trenches are created (see top ...
