Graphene-based tunable plasmonic Bragg reflector with a broad bandwidth.
We propose and numerically analyze a plasmonic Bragg reflector formed in a graphene waveguide. The results show that the graphene plasmonic Bragg reflector can produce a broadband stopband that can be tuned over a wide wavelength range by a small change in the Fermi energy level of graphene. By introducing a defect into the Bragg reflector, we can achieve a Fabry-Perot-like microcavity with a q...
متن کاملPlasmonic Bragg reflector and its application on optical switching
In nowadays intergrated circuit design, the diffraction limit has restricted the downscaling of the conventional electronic components. Surface Plasmon Polaritons (SPPs) are quantized charge density oscillations that occur at the interface between metal and dielectric materials when photons couple to the free electron gas of the metal. The extraordinary properties of SPPs can be utilized for su...
متن کاملHybrid graphene plasmonic waveguide modulators
The unique optical and electronic properties of graphene make possible the fabrication of novel optoelectronic devices. One of the most exciting graphene characteristics is the tunability by gating which allows one to realize active optical devices. While several types of graphene-based photonic modulators have already been demonstrated, the potential of combining the versatility of graphene wi...
متن کاملGraphene Planar Plasmonic Waveguide Devices
Graphene has attracted great attention due to its extraordinary electronic, thermal, mechanical, and optical properties [1]. In photonics, graphene have been exhibited outstanding properties such as transparency, wavelength-independent optical absorption, satuable absorption, electron-hole pair generation, third-order nonlinearity, and electro-absorption. Graphene has been used as a transparent...
متن کاملCharacteristics of Plasmonic Bragg Reflectors with Graphene-Based Silicon Grating
We propose a plasmonic Bragg reflector (PBR) composed of a single-layer graphene-based silicon grating and numerically study its performance. An external voltage gating has been applied to graphene to tune its optical conductivity. It is demonstrated that SPP modes on graphene exhibit a stopband around the Bragg wavelengths. By introducing a nano-cavity into the PBR, a defect resonance mode is ...
