چکیده
|
Most graphene electro-optic modulators based on the electro-refractive modulation are composed of mach-zehnder interferometer or microring resonator structures and have a relative compact size comparing with dielectric ones. to further shrink the footprint, we use the localized surface plasmon resonance of a chain of three metal disks to realize a submicron graphene modulator, whose length can be reduced to less than 1 μm. the proposed graphene modulator has an extinction ratio of 5.5 db with a length of only 740 nm. and the insertion loss, 3-db bandwidth, and power consumption of the modulator are 1.9 db, 83.4 ghz, and 8.55 fj/bit respectively.
