Microwave interferometric technique for characterizing few mode fibers
(2014)
We propose and experimentally demonstrate a simple and accurate technique for measuring differential mode group delay (DMGD) in few mode fibers (FMF). A frequency-swept microwave signal is modulated on a filtered optical ...
Spectral shuffling with phase encoding and dynamic keys applied to transparent optical network signals
(2020-07-01)
A recently proposed signal encryption technique consists in shuffling the samples of two or more baseband signals, which are then modulated in different optical carriers and transmitted by transparent optical networks. In ...

Network performance of optical parametric amplifiers based on tellurite waveguides
(2017-09-01)
Optical parametric amplifiers (OPA) built on glass waveguides are tuneable devices that may be implemented as part of photonic integrated circuits. In this paper, we investigate the performance of recently proposed tellurite ...
