Journal ArticleDOI
High-Speed Optical Phase Modulator Based on Graphene-Silicon Waveguide
TL;DR: In this paper, a high-speed optical phase modulator based on graphene-silicon waveguide (GSW) is presented, where two graphene flakes, sandwiched by insulating dielectric spacers, are embedded in a silicon waveguide to enhance the interaction between the graphene and light.
Journal ArticleDOI
Polarization-Independent Modulator by Partly Tilted Graphene-Induced Electro-Absorption Effect
TL;DR: In this paper, a polarization-independent graphene-based electro-absorption optical modulator concept is presented, which is based on a slanted silicon stripe upon which two graphene flakes reside; on this surface, another silicon waveguide is capped, forming a rectangular silicon-graphene waveguide.
Journal ArticleDOI
Graphene-Assisted Electroabsorption Optical Modulator Using D-Microfiber
TL;DR: In this article, two-lamellae of graphene embedded in the dielectric spacer are incorporated with a side-polished microfiber to enhance the graphene-light interaction efficiency measured in terms of effective mode index change.
Journal ArticleDOI
Graphene-Assisted Polarization-Insensitive Electro-absorption Optical Modulator
TL;DR: In this paper, a polarization-insensitive optical modulator architecture comprised of silica/Si/hBN/graphene/HBN/Graphene, hBN/hN/gramhene/hBn/GBN/Si stack upon a silica substrate to support transverse electric (TE) and transverse magnetic (TM) polarizing modes with identical absorption is presented.
Journal ArticleDOI
Enhanced Performance of ITO-Assisted Electro-Absorption Optical Modulator Using Sidewall Angled Silicon Waveguide
TL;DR: In this article, an electroabsorption (EA) optical modulator architecture comprised of Si/HfO2/ITO/Si stack upon a silica substrate offers an extinction ratio of 6.81% and insertion loss of 0.019% at the expense of 20 f J/bit.
