Experimental demonstration of an on-chip, passive high-rejection filter in silicon

Physicists at C2N and Institut de Physique de Nice have found a simple and generic strategy to overcome one of the major limitations in the fabrication of on-chip filters. They experimentally demonstrated an optical rejection exceeding 80 dB, without ...

Confined nanoscale sound controls light in a microresonator

Researchers demonstrate a semiconductor device for the tailored generation of Brillouin signals in the ultrahigh 100GHz-THz regime. When traversing a solid material such as glass, a light wave can deposit part of its energy in a mechanical wave, ...
