We demonstrate that the peak-to-background ratio of driven solitons can be greatly improved by harnessing the cavity detuning. We use a driven fiber laser pumped below the lasing threshold to increase the finesse and excite solitons in a very wide ra

We report on the observation of nonlinear dynamics in driven-dissipative Bose-Hubbard dimers using a pair of coupled fiber ring resonators coherently driven by a single laser beam. We comprehensively explore the optical switching arising when scannin

We report on several methods for the chromatic dispersion (CD) compensation in optical fiber offset-QAM-based filterbank multicarrier (FBMC-OQAM) systems. We show that several equalization structures, initially proposed for wireless FBMC-OQAM systems

We present femtosecond pump-probe measurements of the nondegenerate (1960-nm excitation and 1176–1326-nm probe) two-photon absorption spectra of 8-nm GaAs/12nmAl_{0.32}Ga_{0.68}As quantum well waveguides. Experiments were performed with light pulse

Photonic stimulation is a new modality of nerve stimulation, which could overcome some of the electrical stimulation limitations. In this paper, we present the results of photonic stimulation of rodent sciatic nerve with a 1470 nm laser. Muscle activ

We analyze the impact of pump depletion in the generation of cavity solitons in a singly-resonant parametrical oscillator that includes a $\chi^{(3)}$ nonlinear section. We find an analytical expression that provides the soliton existence region usin

The measurement of birefringence variations related to nerve activity is a promising label-free technique for sensing compound neural action potentials (CNAPs). While widely applied in crustaceans, little is known about its efficiency on mammal perip

We propose a methodology to tackle the laser control of a non-stationary dark ro-vibrational state of acetylene (C2H2), given realistic experimental limitations in the 7.7 μm (1300 cm−1) region. Simulations are performed using the Lindblad master

We study the dynamics emerging in the photonic driven dissipative Bose-Hubbard model describing two coupled Kerr cavities. By bifurcation analysis we identify rich dynamics, including oscillatory states, chaotic dynamics as well as spikes.
