Fast Hotspot Detection in SFCLs by Exploiting Strain Response in Optical Fiber Sensing

Luc Thévenaz, Bertrand Dutoit, Zhisheng Yang, Bertrand Dutoit, Nicolo' Riva, Arooj Akbar

Superconducting fault current limiters (SFCLs) can be used to limit fault currents in both meshed DC and AC grids by transitioning from superconducting to resistive state, in the presence of high currents. While the device is theoretically a great way to p ...

Exploring nonlinearities in multimode optical fibers for lasers and computing

Ugur Tegin

Multimode optical fibers are the backbone of telecommunication and medical imaging. When light with high intensity travels through a multimode fiber, photons and matter start to interact and propa-gation becomes nonlinear. The nonlinear propagation of ligh ...

Single-shot observation of breathers from noise-induced modulation instability using heterodyne temporal imaging

Alexey Tikan

We report phase and amplitude measurements of large coherent structures originating from the noise-induced modulation instability in optical fibers. By using a specifically designed time-lens system (SEAHORSE) in which aberrations are compensated, the comp ...
