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 ...

As the demand for innovative materials continues to grow—particularly in response to today's technological and environmental ...

The frequency regime lying in the shortwave infrared (SWIR) has very unique properties that make it ideal for several ...

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 ...
