Amplification on a chip: Research raises hope for erbium-based integrated photonics device

The discovery attains a decades-long goal in the field of photonic integration, in which different small optical components are tightly combined for better performance and ease of fabrication.

Single molecular layer and thin silicon beam enable nanolaser operation at room temperature

For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature.
