Angel Valle
visits the VQCC

On February 12, 2024, we received the visit of Prof. Angel Valle from the Cantabria Institute of Physics. 

Prof. Angel Valle is an expert on the dynamics of the light emitted by semiconductor lasers. His PhD thesis analyzed the fluctuations in that light due to spontaneous emission. After that, he focused on the theoretical study of the transverse and polarization modes of a special type of semiconductor lasers, the so-called vertical cavity lasers (VCSEL). During the last 15 years, he has combined these theoretical studies with experimental investigations. In 2007, he opened, together with Luis Pesquera, the Optical Communications laboratory at the Cantabria Institute of Physics, which he currently coordinates. Recent lines of research include optical frequency comb generation and quantum random number generation for applications in optical communications, spectroscopy and cryptography. The activity of this laboratory has given rise to more than fifty publications in magazines.

During his visit to the VQCC, Prof. Angel Valle gave a talk about gain-switched semiconductor laser for quantum random number generation.
