Silicon nanophotonic integrated devices enabling multiplexed on-chip optical interconnects

摘要

Advanced multiplexing technologies including wavelength-division-multiplexing (WDM), polarization-division multiplexing (PDM), and mode-division multiplexing (MDM) have been utilized as a cost-effective solution to enhance the capacity of an optical-interconnect link. The on-chip (de)multiplexers, including WDM filters, PDM devices, and MDM devices, are the most important key components in a multi-channel multiplexed optical interconnect system. Hybrid (de)multiplexer to enable various multiplexing technologies simultaneously are becoming more and more important to achieve many channels. In this paper we give a review for our recent work on silicon photonic integrated devices for realizing multi-channel multiplexed on-chip optical interconnects.
