Cavity-enhanced zero-phonon emission from an ensemble of G centers in a silicon-on-insulator microring

B. Lefaucher, J. -B. Jager, V. Calvo +13

We report successful incorporation of an ensemble of G centers in silicon-on-insulator (SOI) microrings using ion implantation and conventional nanofabrication. The coupling betwee…

Lasing in Group-IV materials

V. Reboud, D. Buca, H. Sigg +6

Silicon photonics in the near-Infra-Red, up to 1.6 um, is already one of key technologies in optical data communications, particularly short-range. It is also being prospected for…

Optically pumped GeSn micro-disks with 16 % Sn lasing at 3.1 um up to 180K

V. Reboud, A. Gassenq, N. Pauc +13

Recent demonstrations of optically pumped lasers based on GeSn alloys put forward the prospect of efficient laser sources monolithically integrated on a Si photonic platform. For i…

Germanium under high tensile stress: nonlinear dependence of direct band gap vs. strain

K. Guilloy, N. Pauc, A. Gassenq +15

Germanium is a strong candidate as a laser source for silicon photonics. It is widely accepted that the band structure of germanium can be altered by tensile strain so as to reduce…

Lattice strain and tilt mapping in stressed Ge microstructures using X-ray Laue micro-diffraction and rainbow-filtering

Samuel Tardif, Alban Gassenq, Kevin Guilloy +14

Micro-Laue diffraction and simultaneous rainbow-filtered micro-diffraction were used to measure accurately the full strain tensor and the lattice orientation distribution at the su…
