چکیده
A polarization-insensitive graphene-assisted electro-optic modulator is proposed. The orthogonal T-shaped metal slot hybrid plasmonic waveguide allows the polarization-independent propagation of transverse electric field mode and complex mode. By introduction dual-layer graphene on ridge waveguide, modulation depths TE are 0.511 dB/µm 0.502 dB/µm, respectively. 3 dB bandwidth we have proposed about 127 GHz at length 20 ?m. power consumption 72 fJ/bit promised potential applications for on-chip interconnected information transfer processing.

متن کاملUltrashort broadband polarization beam splitter based on a combined hybrid plasmonic waveguide
We propose an ultracompact broadband polarization beam splitter (PBS) based on a combined hybrid plasmonic waveguide (HPW). The proposed PBS separates transverse-electric (TE) and transverse-magnetic (TM) modes using a bent lower HPW with vertical nanoscale gaps and a straight upper HPW with a horizontal nanoscale gap, respectively, without relying on an additional coupling region. This design ...
متن کاملNear-infrared electro-optic modulator based on plasmonic graphene.
We propose a novel scheme for an electro-optic modulator based on plasmonically enhanced graphene. As opposed to previously reported designs where the switchable absorption of graphene itself was employed for modulation, here a graphene monolayer is used to actively tune the plasmonic resonance condition through the modification of interaction between optical field and an indium tin oxide (ITO)...
