Three-dimensional optical network-on-chip router communication system and method based on wavelength allocation

Abstract

The invention relates to a wavelength-allocation-based three-dimensional optical on-chip network router communication system and method. The communication system employs a photoelectric mixing type 3D mesh network topological structure and a novel seven-port clog-free optical router capable of realizing multi-wavelength communication; and when the system is applied to a three-dimensional optical on-chip network, no wavelength conversion is needed. Because of utilization of the optical router, the consumed number of optical devices like micro ring resonators and waveguides and the like is reduced. Besides, according to the communication method, when a node of each layer sends out an optical signal, the employed wavelengths are identical; and optical signals with all wavelengths can be received at all layers, so that problems of severe network congestion, low link utilization rate, and limited expansibility due to utilization of single wavelength communication by the existing optical on-chip network architecture can be solved. Therefore, with the system and method, the network congestion probability can be reduced; the communication delay can be reduced; and the throughput capacity and network saturation point can be improved.
