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 ...

But although about 75% of the Earth is made from silica — or silicon dioxide (SiO 2), the main constituent of silicate minerals such as sand, quartzite or granite — elemental silicon itself is ...

The work has been published in Nature. Using gallium phosphide-on-silicon dioxide technology, the new amplifier attains a net ...

This is then coated with a layer of silicon dioxide -- kind of a silicon rust, which doesn't conduct electricity. On top of this is placed a chemical called photoresist. Flashing a pattern of ...

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 ...

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