THz Interconnect, Complement to Electrical and Optical Interconnects

Abstract: “Interconnect Gap” has been a long-standing big challenge caused by the gap between the ever-increasing data rate demand of inter-/intra- chip communications and the insufficient capabilities. Existing electrical interconnect (EI) and optical interconnect (OI) face grand barriers to completely address the interconnect issues individually. THz Interconnect (TI), utilizing the frequency spectrum sandwiched between microwave and optical frequencies, holds the high potentials to complement EI and OI by leveraging the advantages of both electronics and optics. In this talk, I will present our research activities in the high potential TI field, including THz silicon waveguide channel development, TI system demonstration, dispersion constrained link bandwidth and mitigation schemes such as Frequency Division Multiplexing (FDM) and Mode Division Multiplexing (MDM).
