Metamaterial engineered silicon photonic coupler for whispering gallery mode microsphere and disk resonators
Optical microresonators with high quality factors are key in photonic circuits requiring fine spectral filtering or resonant storage of optical power. Silicon (Si) photonics provides high-performance optoelectronic circuits but yields planar Si microresonators with rather low quality factors (Q …

A strategy for ultra-low power saturable absorbers in the mid-infrared
Saturation of the light-matter interaction is an inherent characteristic of the absorption of electromagnetic waves by atoms, semiconductors, and matter in general. In the solid state, the possibility of judiciously controlling saturation phenomena has important consequences for fundamental physics …

A mechanical frequency comb with an atomically thin material
By efficiently coupling nanoresonators, made up of suspended 2D semiconductor membranes, with an optomechanical platform, physicists from the Center for Nanosciences and Nanotechnologies (C2N, Université Paris-Saclay / CNRS), in collaboration with researchers from Pennsylvania, produced a coherent mechanical frequency …
