Band structure, eigenstates and nonlinear dynamic in a photonic fiber lattice

Abstract :

The subject of this manuscript's research is based on the characterization the dynamics of light in a photonic lattice. Photonic lattice are platform where light can propagate and be precisely analysed. The photonic lattice studied is formed by two fiber coupled ring. The evolution of light inside the lattice is fully describe by one relation. This one is especially challenging to be measured in a single measure. In our study, we propose to measure the complet relation into a single measure thanks to an add-on device.
When the relation is observed, we analyze its structure to describe fundamental propreties of the lattice. Our experimental device offer the possibility to measure various relation but moreover complex physical phenomena such as high pulses formation, coherents structures or pulses interactions.
