Observation of strong magneto plasmonic nonlinearity in bilayer graphene discs

نویسندگان

چکیده

Graphene patterned into plasmonic structures like ribbons or discs strongly increases the linear and nonlinear optical interaction at resonance. The response is governed by hot carriers, leading to a red-shift of plasmon frequency. In magnetic fields, hybridizes with cyclotron resonance, resulting in splitting absorption two branches. Here we present how this can be exploited tune graphene discs. absence field, strong pump-induced increase on-resonant transmission observed, but fields range 3 T change characteristics completely, an inverted nonlinearity. A temperature model provided that describes observed behavior well.

Novel midinfrared plasmonic properties of bilayer graphene.

We study the midinfrared plasmonic response in Bernal-stacked bilayer graphene. Unlike its monolayer counterpart, bilayer graphene accommodates optically active phonon modes and a resonant interband transition at infrared frequencies. They strongly modify the plasmonic properties of bilayer graphene, leading to Fano-type resonances, giant plasmonic enhancement of infrared phonon absorption, a n...

Quantum-enhanced tunable second-order optical nonlinearity in bilayer graphene.

Second order optical nonlinear processes involve the coherent mixing of two electromagnetic waves to generate a new optical frequency, which plays a central role in a variety of applications, such as ultrafast laser systems, rectifiers, modulators, and optical imaging. However, progress is limited in the mid-infrared (MIR) region due to the lack of suitable nonlinear materials. It is desirable ...

Influence of interlayer asymmetry on magneto-spectroscopy of bilayer graphene

We present a self-consistent calculation of the interlayer asymmetry in bilayer graphene caused by an applied electric field in magnetic fields. We show how this asymmetry influences the Landau level spectrum in bilayer graphene and the observable inter-Landau level transitions when they are studied as a function of high magnetic field at fixed filling factor as measured experimentally in Ref. ...

Observation of low energy Raman modes in twisted bilayer graphene.

Two new Raman modes below 100 cm(-1) are observed in twisted bilayer graphene grown by chemical vapor deposition. The two modes are observed in a small range of twisting angle at which the intensity of the G Raman peak is strongly enhanced, indicating that these low energy modes and the G Raman mode share the same resonance enhancement mechanism, as a function of twisting angle. The ~94 cm(-1) ...
