Chip-based tunable all-optical logic gates via four-wave mixing in graphene-on-silicon microresonators

摘要

We present a practical tunable all-optical logic gate based on the FWM effect in the graphene-on-silicon (GoS) microresonator. The GoS microresonator could produce broadband flat dispersion with multiple zero-dispersion wavelengths (ZDWs) by electrically tuning the graphene. © 2020 The Author(s)
