The temporal analogue of diffractive couplers
Anastasiia Sheveleva, Pierre Colman, Christophe Finot
Based on the space-time duality of light, we numerically demonstrate that temporal dispersion grating couplers can generate from a single pulse an array of replicas of equal amplit…
Modelling self-similar parabolic pulses in optical fibres with a neural network
Sonia Boscolo, John M. Dudley, Christophe Finot
We expand our previous analysis of nonlinear pulse shaping in optical fibres using machine learning [Opt. Laser Technol., 131 (2020) 106439] to the case of pulse propagation in the…
Nonlinear Compression of Besselon Waves for High Repetition-Rate Subpicosecond Pulses Trains
Anastasiia Sheveleva, Christophe Finot
We theoretically and experimentally demonstrate the generation of high-quality low duty-cycle pulse trains at repetition rates of 28 GHz, 56 GHz and 112 GHz. Starting from a contin…
A Peregrine soliton-like structure that has nothing to deal with a Peregrine breather
Christophe Finot
We report on experimental results where a temporal intensity profile presenting some of the main signatures of the Peregrine soliton (PS) is observed. However, the emergence of a h…
Vectorial dispersive shock waves on an incoherent landscape
Javier Nuño, Christophe Finot, Julien Fatome
We study numerically and experimentally the impact of temporal randomness on the formation of analogue optical blast-waves in nonlinear fiber optics. The principle-of-operation is…
Temporal Fresnel diffraction induced by phase jumps in linear and nonlinear optical fibres
Anastasiia Sheveleva, Christophe Finot
We analytically and numerically study the temporal intensity pattern emerging from the linear or nonlinear evolutions of a single or double phase jump in an optical fiber. The resu…
