Abstract

The invention provides a four-port optical router based on micro-ring resonant optical switches. The four-port optical router comprises six crossed waveguides and four micro-ring resonant optical switches, wherein the Add end of the first micro-ring resonant optical switch serves as a first input port of the router, and the Drop end of the first micro-ring resonant optical switch serves as a second output port of the router; the Drop end of the second micro-ring resonant optical switch serves as a second input port of the router, and the Add end of the second micro-ring resonant optical switch serves as a first output port of the router; the Input end of the third micro-ring resonant optical switch serves as a third output port of the router, and the Drop end of the third micro-ring resonant optical switch serves as a fourth output port of the router; the Input end of the fourth micro-ring resonant optical switch serves as a third input port of the router, and the Drop end of the fourth micro-ring resonant optical switch serves as a fourth input port of the router. According to the router, the quantity of the micro-ring resonant optical switches is reduced and optical losses are reduced; the four-port optical router is easy for large-scale integration, lower in power consumption, small in volume, less in time delay and rapid in speed, and plays an important role in a high-performance processing unit for photon communication.

Description

technical field [0001] The invention belongs to the technical field of on-chip optical interconnection, and relates to a four-port optical router based on a microring resonator (MRR) optical switch. Background technique [0002] With the rapid development of semiconductor technology, the integration of chips or integrated circuits is getting higher and higher, and the CPU can already obtain GHz-level operating frequency, but the most serious problem brought about by high frequency is that the power consumption per unit area of ​​the circuit rises sharply At the same time, due to the further reduction in the size of integrated components, the leakage and heat dissipation problems cannot be solved well, and Moore's Law is constantly being challenged. There are various indications that the use of electrons as information carriers can no longer meet people's requirements for faster processing speeds, while optical-optical communication and optical computing systems use photons a...
