Optical network-on-chip system supporting multicast communication

Abstract

The invention discloses an optical network-on-chip system supporting multicast communication. The optical network-on-chip system supporting multicast communication mainly solves the problems that an existing optical network-on-chip is low in multicast communication efficiency and complex in network structure, and blocking exists. The optical network-on-chip system structurally comprises a two-stage optical switching network, an IP core, an electric-to-optical conversion unit and an optical-to-electric conversion unit. The two-stage optical switching network is composed of a first stage optical switching network and a second stage optical switching network. Through reasonable arrangement of waveguides and multi-wavelength micro-ring resonators in the first stage optical switching network and waveguides and multi-wavelength micro-ring resonators in the second stage optical switching network, the situation that each communication node can transmit optical signals to all the other communication nodes simultaneously can be guaranteed, and therefore a multicast communication function is achieved. According to the optical network-on-chip system, due to the use of the multi-wavelength micro-ring resonators, the number of micro-ring resonators is reduced, and complexity of the networks is lowered. The optical network-on-chip system can effectively improve the multicast communication efficiency of the optical network-on-chip, simplifies the structure of the optical switching network, and is suitable for inter-core optical interconnection of the optical network-on-chip.
