Graphene has emerged as an attractive material for a myriad of optoelectronic applications due to its variety of remarkable optical, electronic, thermal and mechanical properties. So far, the main focus has been on graphene based photonics and optoelectronics devices. Due to the linear band structure allowing interband optical transitions at all photon energies, graphene has remarkably large third-order optical susceptibility χ (3) , which is only weakly dependent on the wavelength in the near-infrared frequency range. Graphene possesses the properties of the enhancement four-wave mixing (FWM) of conversion efficiency. So, we believe that the potential applications of graphene also lies in nonlinear optical signal processing, where the combination of its unique large χ (3) nonlinearities and dispersionless over the wavelength can be fully exploited. In this chapter, we give a brief overview of our recent progress in graphene-assisted nonlinear optical device which is graphene-coated optical fiber and graphene-silicon microring resonator and their applications, including degenerate FWM based tunable wavelength conversion of quadrature phase-shift keying (QPSK) signal, two-input optical computing, three-input high-base optical computing, graphene-silicon microring resonator enhanced nonlinear optical device for on-chip optical signal processing, and nonlinearity enhanced graphenesilicon microring for selective conversion of flexible grid multi-channel multi-level signal.

“…The properties of massless Dirac fermions also lead to that the frequency of 2D plasmons in graphene scales as the electron density raised to 1/4, 13,14 in contrast to that of Schr€ odinger electrons 21,22 where the frequency of 2D plasmons scales as the square root of the electron density. Nonlinear photonics have important applications in graphene with respect to harmonic generation and nonlinear electrodynamic response, [23][24][25][26][27][28] broadband optical limiting application, 29 four-wave mixing frequency conversion, [30][31][32] nonlinear generation of plasmons, 33 and other applications. [34][35][36] The self-interaction among large amplitude 2D plasmons leads to harmonic generation, 37 and their sidebands could be an important source of instability and localization of wave energy.…”

A nonlinear fluid model of high-frequency plasmons in doped graphene is derived by taking fluid moments of the semi-classical kinetic equation for the electron gas. As a closure of the fluid moments, adiabatic compression is assumed with a given form of the distribution function, combined with an exact linear response based on the linearized Vlasov-Poisson system. In the linear regime, the model is in the long wavelength limit consistent with previous results using the random phase approximation for a two-dimensional electron gas, while it neglects the short-range interactions between massless Dirac fermions. The fluid model may be used to study the non-linear plasmonic wave mixing and optical coupling to lasers in graphene.

“…Experiments have shown that Dirac plasmons in graphene on SiC are hybridized with optical phonons of the SiC substrate [13], while scattering of plasmons off capillary waves (riplons) were observed in an electron sheet on liquid helium [1]. Nonlinear photonics have important applications in graphene with respect to harmonic generation [14], optical and plasmonic bistability [15,16], broadband optical limiting application [17], four-wave mixing frequency conversion [18], and other nonlinear photonic applications [19]. On the other hand, the self-interaction among large amplitude 2D plasmons and their sidebands could be an important source of instability and localization of wave energy.…”

The nonlinear electron dynamics in a two-dimensional (2D) plasma layer are investigated theoretically and numerically. In contrast to the Langmuir oscillations in a three-dimensional (3D) plasma, a wellknown feature of the 2D system is the square root dependence of the frequency on the wavenumber, which leads to unique dispersive properties of 2D plasmons. It is found that for large amplitude plasmonic waves there is a nonlinear frequency upshift similar to that of periodic gravity waves (Stokes waves). The periodic wave train is subject to a modulational instability, leading to sidebands growing exponentially in time. Numerical simulations show the breakup of a 2D wave train into localized wave packets and later into wave turbulence with immersed large amplitude solitary spikes. The results are applied to systems involving massless Dirac fermions in graphene as well as to sheets of electrons on liquid helium.
