Fully Mapped Light Communication Network on Chip
Abstract
A fully mapped light communication network is demonstrated on gallium nitride (GaN) chips, wherein closed-loop communication units are enabled by GaN multiquantum-well diodes with light emission and detection functionalities. Bidirectional light communication between two nodes is achieved over a single waveguide under a time division duplexing scheme, while on-chip relay light communication is realized among three nodes. Three interconnected closed-loop units form a nine-node light communication network, enabling on-chip seamless video transmission. The decentralized and reconfigurable on-chip light communication network architecture is experimentally verified, providing a feasible route toward next-generation all-light information processing and system-on-chip computation.
