Theory and Design of Adiabatically Tapered Multimode Interference Couplers

Tapered-multimode-interference (MMI) splitters and couplers result in more compact designs than conventional MMI devices. In this paper, we analyze the adiabatic limit of the tapered MMI and present new designs that are both compact and result in minimal loss
