dc.description.abstractTwo-dimensional materials herald the coming of advances in many areas of Engineering, thanks to the peculiar physicochemical properties obtained when one isolates a single layer of minerals such as graphite and black phosphorus, for example. In the field of optical communications, graphene, composed by only one layer obtained from graphite, has been conquering prominence in applications regarding electro-optic modulators. Graphene exhibits potential to diminish the size and energy consumption of integrated photonic devices operating in the C-band of telecommunications (1550 nm), as well as to increase their transmission rates. The use of graphene on integrated photonics devices has been proposed and demonstrated with encouraging results concerning binary amplitude modulation. By means of computational simulations on COMSOL MultiPhysics v5.3 software, graphene-based electro-optical modulators for PAM-4 multilevel amplitude modulation with no requirement of digital-to-analog conversion (DAC) were designed in this work. The PAM-4 format allows a two-fold increase compared to the binary format without escalating the electro-optical bandwidth. Hence, modulation speeds higher than 200 Gbit/s are calculated from the fashioned devices with electro-optical bandwidths of 83,3 GHz. Recently, two-dimensional black phosphorus has also been explored for applications in modulators operating on the mid-infrared regime. Simulations were realized evaluating the use of black phosphorus on the 1550 nm wavelength regarding amplitude modulation for performance confrontation with graphene. It is shown that when compared with monolayer graphene, black phosphorus would display superior functioning if employed starting from a thickness corresponding to 12 layers.eng
