Abstract

The invention discloses a five-port nonblocking optical router based on micro-ring resonators. The five-port nonblocking optical router comprises a first micro-ring resonator, a second micro-ring resonator, a third micro-ring resonator, a fourth micro-ring resonator, a fifth micro-ring resonator, a sixth micro-ring resonator, a seventh micro-ring resonator, an eighth micro-ring resonator, a ninth micro-ring resonator, a tenth micro-ring resonator, an eleventh micro-ring resonator, a twelfth micro-ring resonator, a thirteenth micro-ring resonator, a fourteenth micro-ring resonator, a fifteenth micro-ring resonator, a first optical waveguide, a second optical waveguide, a third optical waveguide, a fourth optical waveguide and a fifth optical waveguide, wherein one end of the first optical waveguide is a first input end and the other end of the first optical waveguide is a fifth output end; one end of the second optical waveguide is a second input end and the other end of the second optical waveguide is a first output end; one end of the third optical waveguide is a third input end and the other end of the third optical waveguide is a second output end; one end of the fourth optical waveguide is a fourth input end and the other end of the fourth optical waveguide is a third output end; and one end of the fifth optical waveguide is a fifth input end and the other end of the fifth optical waveguide is a fourth output end. By using the five-port nonblocking optical router based on the micro-ring resonators, eastern, southern, western, northern and local nonblocking free communication is realized, the average losses and crosstalk of links are reduced and an optical network-on-chip is enabled to have better extensibility.

Description

technical field [0001] The invention relates to the technical field of node interconnection in an on-chip optical interconnection network system, in particular to a five-port non-blocking optical router based on a microring resonator. Background technique [0002] Today's processors are developing towards multi-core. However, as the number of processor cores continues to increase, the main frequency continues to increase, and the bandwidth required for communication between cores also continues to increase. The traditional electrical interconnection has high power consumption, high delay, large signal distortion, and limited bandwidth, which can no longer adapt to this development trend. The solution of using on-chip optical interconnection network is expected to be able to solve this problem well. [0003] Routers are the core devices for building networks. Currently, on-chip optical routers include wavelength routers based on wavelength selection and routers based on dynam...
