However, a key problem with most modern lasers is that they emit light at fixed wavelengths. This limitation can be overcome using quantum dots, nanoscale semiconductors that can emit light of ...

Supraparticle lasers work by trapping light inside a tiny sphere made of special particles called quantum dots, which can absorb, emit, and amplify light very efficiently. They are made by mixing ...

Quantum dot FP lasers have an ensemble of self-assembled QDs inside the cavity as shown in Fig. 1. By simply modulating the laser's injection current, the laser emits a stream of digital data bits ...
