Method for real-time measurement of the nonlinear refractive index
(American Institute of Physics, 2019-09)
In this work, we propose a novel method for continuous real-time measurement of the dynamics of the nonlinear refractive index n2. This is particularly important for characterizing phenomena or materials (such as biological ...
Photon-conserving generalized nonlinear Schrödinger equation for frequency-dependent nonlinearities
(Optical Society of America, 2020-01)
Pulse propagation in nonlinear waveguides is most frequently modeled by resorting to the generalized nonlinear Schrödinger equation (GNLSE). In recent times, exciting new materials with peculiar nonlinear properties, such ...
Latest advances in optical frequency combs based on quadratic non-linearity
(Institution of Engineering and Technology, 2020-06)
Second-order non-linear susceptibility (χ2) is the cause of many non-linear processes in optics including second harmonic generation, sum frequency generation and difference frequency generation. Optical frequency combs ...
Giant and Tunable Optical Nonlinearity in Single-Crystalline 2D Perovskites due to Excitonic and Plasma Effects
(Wiley VCH Verlag, 2019-07)
Materials with large optical nonlinearity, especially in the visible spectral region, are in great demand for applications in all-optical information processing and quantum optics. 2D hybrid Ruddlesden−Popper-type halide ...
Modified nonlinear Schrödinger equation for frequency-dependent nonlinear profiles of arbitrary sign
(Optical Society of America, 2019-10)
In recent times, materials exhibiting frequency-dependent optical nonlinearities, such as nanoparticle-doped glasses and other metamaterials, have gathered significant interest. The simulation of the propagation of intense ...
