Linewidth narrowing in self-injection-locked, on-chip lasers

On-chip laser diodes based on quantum well (QW) and quantum dot (QD) semiconductor materials have become the primary technology for several applications due to their excellent characteristics, including high power efficiency, ...

Buckle up: A new class of materials is here

Usually, the two characterizations of a material are mutually exclusive: something is either stiff, or it can absorb vibrations well—but rarely both. However, if we could make materials that are both stiff and good at absorbing ...
