Quench, Glow, or Stay Silent: Distance-Controlled Up-Conversion Emission near Metallic Nanowires
Maciej Cwierzona, Michal Zebrowski, Pavel Dziarhai +5
We demonstrate controlled transitions between competing radiative and nonradiative decay channels in the up-conversion luminescence of NaYF4:Er3+/Yb3+ nanocrystals placed in proxim…
Optimum design of NOLM-driven mode-locked fiber lasers
Alix Malfondet, Alexandre Parriaux, Katarzyna Krupa +2
Most of the saturable absorbers commonly used to perform mode locking in laser cavities affect the trigger conditions of laser oscillation, which requires manually forcing the lase…
Semi-linear all-polarization-maintaining Yb-doped fiber laser oscillator manifesting dual operation regime at net anomalous dispersion
Mateusz Pielach, Agnieszka Jamrozik, Katarzyna Krupa +1
Ultrafast all-fiber Yb-doped fiber oscillators are usually associated with all-normal-dispersion cavities, which operate in a dissipative soliton regime, quintessential for pulsed…
Observation of light thermalization to negative temperature Rayleigh-Jeans equilibrium states in multimode optical fibers
K. Baudin, J. Garnier, A. Fusaro +5
Although the temperature of a thermodynamic system is usually believed to be a positive quantity, under particular conditions, negative temperature equilibrium states are also poss…
Multimode optical fiber beam-by-beam cleanup
Mario Ferraro, Fabio Mangini, Yann Leventoux +8
We introduce and experimentally demonstrate the concept of all-optical beam switching in graded-index multimode optical fibers. Nonlinear coupling between orthogonally polarized se…
Tailoring 2D Fast Iterative Filtering algorithm for low-contrast optical fringe pattern preprocessing
Mikolaj Rogalski, Mateusz Pielach, Antonio Cicone +6
Retrieving object phase from the optical fringe pattern is a critical task in quantitative phase imaging and often requires appropriate image preprocessing (background and noise mi…
Studying the operation of an all-PM Yb-doped fiber laser oscillator at negative and positive net cavity dispersion
Mateusz Pielach, Jan Szczepanek, Katarzyna Krupa +1
Chirped fiber Bragg gratings in Yb-doped fiber lasers allow tuning the net cavity dispersion, thus enabling access to pulse dynamics beyond the typical all-normal-dispersion dissip…
Frequency-Resolved Spatial Beam Mapping in Multimode Fibers: Application to Mid-Infrared Supercontinuum Generation
Y. Leventoux, G. Granger, K. Krupa +6
We present a new spatial-spectral mapping technique permitting to measure the beam intensity at the output of a graded-index (GRIN) multimode fiber with sub-nanometric spectral res…
Decomposing spatial mode superpositions with a triangular optical cavity
G. H. dos Santos, D. C. Salles, M. G. Damaceno +5
We demonstrate that a triangular cavity can operate as an efficient discriminator for Hermite-Gaussian optical modes. The process is applied to distinct fields produced by a Spatia…
Energy and wave-action flows underlying Rayleigh-Jeans thermalization of optical waves propagating in a multimode fiber
K. Baudin, A. Fusaro, J. Garnier +6
The wave turbulence theory predicts that a conservative system of nonlinear waves can exhibit a process of condensation, which originates in the singularity of the Rayleigh-Jeans e…
3D time-domain beam mapping for studying nonlinear dynamics in multimode optical fibers
Y. Leventoux, G. Granger, K. Krupa +8
The characterization of the complex spatiotemporal dynamics of optical beam propagation in nonlinear multimode fibers requires the development of advanced measurement methods, capa…
Rayleigh-Jeans condensation of classical light : Observation and thermodynamic characterization
K. Baudin, A. Fusaro, K. Krupa +4
Theoretical studies on wave turbulence predict that a purely classical system of random waves can exhibit a process of condensation, in analogy with the quantum Bose-Einstein conde…
Frequency-doubled femtosecond Er-doped fiber laser for two-photon excited fluorescence imaging
Dorota Stachowiak, Jakub Bogusławski, Aleksander Głuszek +3
A femtosecond frequency-doubled Erbium-doped fiber laser with adjustable pulse repetition rate is developed and applied in two-photon excited fluorescence microscopy. The all-fiber…
Planar waveguide nanolaser configured by dye-doped hybrid nanofilm on substrate
E. A. Tikhonov, V. P. Yashchuk, G. M. Telbiz
Dye-doped hybrid silicate/titanium nanofilms on the glass substrate in the structure of asymmetrical waveguides were studied as the laser system. The spatial and spectral features…
