Silicon nanophotonic integrated devices for networks-on-chip: Multiplexing and switching

In this paper we give a review on silicon nanophotonic integrated devices for networks-on-chip, including hybrid (de)multiplexers enabling more than two popular multiplexing technologies like wavelength-division-multiplexing (WDM), polarization-division-multiplexing (PDM), as well as mode-division-multiplexing (MDM). Recent progresses on thermal-switchable silicon photonic devices are also discussed regarding the increasing demands for reconfigurable photonic networks-on-chip.
