The chip starts out as a thin wafer of P-type silicon. 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 ...

T oday, silicon photonic circuits connect server racks and play key roles in chemical sensors, biosensors, and LIDAR for self ...

But although about 75% of the Earth is made from silica — or silicon dioxide (SiO 2), the main ... polycrystalline silicon used to make silicon wafers (smooth thin discs). The richness of ...

For that reason, the direct epitaxial growth of high-quality III-V optical gain materials selectively on large-size silicon photonics wafers remains a highly sought-after objective.” The large ...

Researchers at Osaka University in Suita, Japan, have devised a novel way to improve the performance of electronic devices. The study, published in ACS Applied Electronic ...

Imec has demonstrated electrically-driven GaAs-based multi-quantum-well nano-ridge laser diodes fully, monolithically fabricated on 300 mm silicon wafers in its CMOS pilot prototyping line. Achieving ...
