We study the strong dynamic input-output decoupling problent (SDIODP) for nonlinear systetls' It is shown that, given a generically satisfied assumption, the solvability of tlie SDIODP around an equilibriurn point is equivalent to the solvability ofthc satne problem for the linearization of the system arourrd this equilibrium point. We introduce the Singh compensator, a dynamic state feedback o...

The nonlinear equations of motion such as the Duffing oscillator equation and its family are seldom addressed in intermediate instruction classical dynamics; this one is problematic because it cannot be solved terms elementary functions before. Thus, work, stability analysis quadratic damping higher-order nonlinearity investigated. Hereinafter, some new analytical solutions to undamped form Wei...

We use pump-probe spectroscopy and continuous wave cross-phase and cross-amplitude modulation measurements to study the optical nonlinearity of a hydrogenated amorphous silicon (a-Si:H) nanowire waveguide, and we compare the results to those of a crystalline silicon waveguide of similar dimensions. The a-Si:H nanowire shows essentially zero instantaneous two-photon absorption, but it displays a...

A radio over fiber (RoF) system is a kind of analog optical transmission system and considered as a strong candidate for the next-generation fronthaul link in the future mobile network. In RoF systems, nonlinearity compensation is essential to increase the link capacity. In this paper, we propose a nonlinearity detection and compensation scheme using a monitoring channel in RoF systems. A monit...

Nonlinear optical materials comprise the foundation of modern photonics, offering functionalities ranging from ultrafast lasers to optical switching, harmonic and soliton generation. Optical nonlinearities are typically strong near the electronic resonances of a material and thus provide limited tuneability for practical use. Here we show that in plasmonic nanorod metamaterials, the Kerr-type n...
