In this Research Letter, using experimental data, we analyze the computational complexity of modulation instability of a light wave propagating in a single-mode optical fiber. We show that computational complexity is an excellent tool which provides

Modelocked lasers are typically modeled using the Haus master equation which, albeit powerful, provides only a limited description in certain parameter regimes. The authors introduce another master equation formalism to describe laser modelocking tha

In normal dispersion, modulation instability, which is a precursor of Kerr combs, is forbidden due to phase mismatch. Here, the authors show the compensation of such phase mismatch by introducing frequency-dependent loss using a notch filter, hence l

Dissipative Faraday instability by periodic zig-zag modulation of spectral losses can lead to pattern formation in variety of systems. Here, the authors employ this nonlinear instability as a technique to achieve high-order harmonic mode-locking in a

We present the theory of parametric amplification in coupled nonlinear waveguides considering the frequency dependency of the coupling strength. We show that coupling dispersion can indeed compensate for the uncoupled individual waveguides dispersion

We present an analytical and numerical study of optical parametric amplification in coupled waveguides amplifiers accounting for presence of losses and spatially dependent coupling. Spatially dependent coupling enables to compensate for mismatch dyna

We study theoretically an optical parametric amplifier made of two coupled waveguides, accounting for losses and spatially dependent coupling, and show that it can have improved performances compared to the standard single waveguide version.

Parametric amplifiers relying on the nonlinear four-wave mixing process are known for their signature symmetric gain spectrum, where signal and idler sidebands are generated on both sides of a powerful pump wave frequency. In this article we show ana
