Generation of a guided-wave “Bessel-Gaussian” beam using an integrated 2D array of plasmonic nanoresonators

Researchers at the Centre de Nanosciences et de Nanotechnologies (C2N), in collaboration with Laboratoire Interdisciplinaire Carnot de Bourgogne (ICB) have demonstrated the generation of a non-diffractive guided-wave optical beam over a long distance. The exploited concept of Bessel beam, ...

A supercontinuum light source in the O-band communication window, compatible with industrial CMOS processes

A team of researchers at C2N, in a collaboration with STMicroelectronics, have demonstrated a two-octave spanning supercontinuum generation in the O-band, a major communication window. These are the first results reported using a silicon nitride waveguide on a “back-end-of-line” ...

First ultra-low threshold continuous-wave lasing in Germanium-Tin

Transistors in computer chips work electrically, but the data can be transmitted more quickly with light. Researchers have therefore been looking for a way to integrate a laser directly into silicon chips for a long time. Researchers at C2N, ...
