Effective electro-optic modulation in low-loss graphene-plasmonic slot waveguides
Yunhong Ding, Xiaowei Guan, Xiaolong Zhu +6
Surface plasmon polaritons enable light concentration within subwavelength regions, opening thereby new avenues for miniaturizing the device and strengthening light-matter interact…
Slow-light-enhanced energy efficiency for the graphene microheater on silicon photonic crystal waveguides
Siqi Yan, Xiaolong Zhu, Lars Hagedorn Frandsen +4
Slow light has been widely utilized to obtain enhanced nonlinearities, enhanced spontaneous emissions, and increased phase shifts owing to its ability to promote light-matter inter…
Graphene-plasmon polaritons: From fundamental properties to potential applications
Sanshui Xiao, Xiaolong Zhu, Bo-Hong Li +1
With the unique possibilities for controlling light in nanoscale devices, graphene plasmonics has opened new perspectives to the nanophotonics community with potential applications…
Effective electro-optical modulation with high extinction ratio by a graphene-silicon microring resonator
Yunhong Ding, Xiaolong Zhu, Sanshui Xiao +4
Graphene opens up for novel optoelectronic applications thanks to its high carrier mobility, ultra-large absorption bandwidth, and extremely fast material response. In particular,…
Experimental observation of plasmons in a graphene monolayer resting on a two-dimensional subwavelength silicon grating
Xiaolong Zhu, Wei Yan, Peter Uhd Jepsen +3
We experimentally demonstrate graphene-plasmon polariton excitation in a continuous graphene monolayer resting on a two-dimensional subwavelength silicon grating. The subwavelength…
Bends and splitters in graphene nanoribbon waveguides
Xiaolong Zhu, Wei Yan, N. Asger Mortensen +1
We investigate the performance of bends and splitters in graphene nanoribbon waveguides. Although the graphene waveguides are lossy themselves, we show that bends and splitters do…
