Scalable Classical and Quantum Light Sources

The scaling of lasers and in-particular of surface emitting lasers is a multi-decade long question that has been investigated since the invention of lasers in 1958. It is an important question with numerous applications. In this talk, I will propose and discuss an intriguing solution to this question that we named the Berkeley Surface Emitting Laser (BerkSEL) and it is the world’s first scale-invariant laser. In the second part of the talk, I will discuss our demonstration of the first deterministic quantum light source in silicon that emits single photons in the telecom band. The work opens unique perspectives for scalable quantum networks.
