Silicon phase and intensity modulators for flat frequency comb generation

References Optical frequency combs are an essential tool in many fields. To generate them, it is possible to exploit silicon photonics phase and amplitude modulators. In this work we numerically investigate the performance of such devices for the generation …

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 …
