Abstract: (2269 Views)
All optical-modulator is a new generation of modulators designed in conjunction with electro-absorbing modulators to improve performance, increase speed and reduce the power of these modulators. Graphene has also been used for this kind of modulator because of its unique optical properties. In this paper, an all optical graphene modulator is modeled numerically and the uniqe role of graphene has also been shown in this analysis. For the analysis , a single-mode optical fiber is considered and drawned from it’s two sides and narrowed, Then on the narrowed portion a graphene layer was coverd and the results are checked. Finally, a layer of polymer is also coverd on graphene and it’s Performance improvements is shown. In this research, the effect of fiber stretching on modulation depth and power consumption has been investigated. Reducing the radius of the narrowed section from 1 to 0.4 μm will significantly improve the depth of modulation and reduce power. Adding an extra polymer layer to graphene has reduced power consumption.
