Numerical simulations of tunable ultrashort power splitters based on slotted multimode interference couplers
This paper presents an ultracompact tunable device for power splitting and switching by tuning the Fermi energy level of monolayer patternless graphene underneath a slotted multimode interference (MMI) coupler operating in the mid-infrared, λ = 9–11 μm. By introducing a high-index silicon slot in th...
