Numerical stability of solitons waves through splices in quadratic optical media
Acta Scientiarum: Technology, 2020 The propagation of soliton waves is simulated through splices in quadratic optical media, in which fluctuations of dielectric parameters occur. A new numerical scheme was developed to solve the complex system of partial differential equations (PDE) that

Pulse Generation by On‐Chip Dispersion Compensation at 8 µm Wavelength
Laser &Photonics Reviews, EarlyView.This work demonstrates on‐chip pulse generation at 8 μm$\mathrm{\mu}\mathrm{m}$ using chirped Bragg gratings in SiGe graded‐index photonic circuits to compensate the quadratic phase of quantum cascade laser frequency combs. With this approach pulses as short as 1.39 ps were produced, close to the transform limit, representing a key step toward compact,

Soliton sheets of Bose–Einstein condensates in optical lattices
New Journal of PhysicsSoliton sheets are observed in Bose–Einstein condensates in optical lattice which are formed by superposition of condensates occupying different single-particle states. These structures consist of one-dimensional stationary solitons distributed in the x -
