Research project integrates laser directly on silicon with a modulator

IRT Nanoelec, an R+D consortium focused on information and communication technologies using micro- and nanoelectronics, today announced the first co-integration of a III-V/silicon laser and silicon Mach Zehnder modulator demonstrating 25 Gbps transmission on a single channel. This transmission rate usually is achieved using an external source, over a 10 km single-mode fiber.

The metal-insulator transition depends on the mass of the Dirac electrons

Scientists have used powerful supercomputers to perform a large-scale analysis of the behavior of electrons in a material transitioning from a metal to an insulator phase.

Scientists develop new technique for imaging cells and tissues under the skin

A team of scientists developed the first technique for viewing cells and tissues in 3 dimensions under the skin - the work could improve diagnosis and treatment for some forms of cancer and blindness.

Nano plates as catalysts for solar fuels

Researchers nvestigated special nanoplates with platinum particles on them, accelerating the chemical conversion. During his research, they discovered why the effect of these particles is less than commonly expected.

Real-time direct observation of atom movements in electron microscopy

Atomic motion in a crystalline oxide that was used as a cathode in Li-ion batteries was directly demonstrated by state-of-an-art transmission electron microscopy, revealing the transient pathway of a chemical ordering reaction.
