Low-loss four-port non-blocking optics router based on micro-ring resonator

Abstract

The invention discloses a low-loss four-port non-blocking optics router based on micro-ring resonators. Through six cross waveguide micro-ring resonators and a parallel waveguide micro-ring resonator, an input end of a first port is coupled to an output end of a fourth port. An input end of a second port is coupled to an output end of the first port. An input end of the fourth port is coupled to an output end of a third port. The input end of the first port is coupled to the output end of the third port. An input end of the third port is coupled to an output end of the second port. The input end of the second port is coupled to the output end of the fourth port. A seventh micro-ring resonator is used for being connected with an optical channel from the fourth port to the first port and an optical channel from the second port to the third port. Due to the fact that the number of the micro-ring resonators is reduced to seven, the low-loss four-port non-blocking optics router based on the micro-ring resonators has the advantages of improving utilization efficiency of devices, simplifying the structure of a switch, decreasing area of the switch, reducing insertion loss and crosstalk of the switch due to the fact that the number of the cross waveguide micro-ring resonators is reduced to six, enhancing extendibility of the devices, being prone to establishing an on-chip optical interconnection network architecture and achieving high-speed transmission and exchange of optical signals.

Description

technical field [0001] The invention relates to the technical field of switches for realizing routing switching between multiple ports in an on-chip optical interconnection network architecture, in particular to a 4×4 non-blocking low-loss optical router based on an active microring resonator. Background technique [0002] With the development of semiconductor technology, the integration of a single processor has been significantly improved, and the number of processor cores on a chip has been steadily increased. The thousand-core era is quietly moving towards us, making the efficiency of data movement between cores a key factor restricting the overall performance of the processor. How to meet the bandwidth and delay requirements of future multi-core systems with low energy consumption has become a major challenge in the field of optoelectronic integration. [0003] Traditional on-chip interconnection technology is restricted by the physical characteristics of electrical int...
