Phase synchronization dynamics of two mutually coupled InP lasers in a quantum entropy source
Berta MartÃnez-Pà mias, Miquel Rudé, Cristina Masoller
The paper investigates how residual coupling between two gain‑switched InP lasers in a photonic integrated circuit leads to phase synchronization, affecting the entropy of a quantu…

Identifying and anticipating the threshold bifurcation of a complex laser with permutation entropy
Juan Gancio, Cristina Masoller, Mathias Marconi
The permutation entropy (PE) is a statistical indicator that allows to quantify the complexity of a signal. Here we show that it is able to {identify and anticipate} the threshold…
