We report observation of oscillations in the dynamics of a microcavity polariton condensate formed under pulsed non resonant excitation. While oscillations in a condensate have always been attributed to Josephson mechanisms due to a chemical potentia

In recent years, it has become clear that Distributed Acoustic Sensing (DAS) is capable of capturing many seismic signals, including earthquakes across a range of magnitudes. Given the vast networks of fibre optic cables beneath urban areas, there is

Delay differential equations enriched with nonlinear gain compression for passively mode-locked semiconductor lasers

Autor: Simos, C. Simos, I. Georgiou, G.

Non-linear gain compression is well-known to play an important role in the dynamics of short-pulse generation and propagation in semiconductor lasers. Here, a previously reported delay differential equation model for passively mode-locked semiconduct
