Resumo
© 2018 IEEE. Silicon photonics-based optical modulators embedded with graphene have been demonstrated operating in bandwidths ranging from 2.7 to 30 GHz. Such devices sport compact footprints (μm 2 range, against todays mm 2 areas) and demand low energy per bit values (sub-pJ range) for high-speed applications in the C-band of telecommunications (1550 nm). This paper contributes by examining the role that resistance and capacitance optimization play in increasing electro-optical bandwidth and reducing energy per bit consumption, as well as the limits concerning these improvements by approaching previously proposed architectures through updated resistance reduction techniques and a more realistic analysis regarding device's capacitance.
