Description

technical field [0001] The invention belongs to the field of optical logic computing, and relates to a control switching gate optical logic device based on a microring resonator, which is suitable for the fields of optical communication and optical computing. Background technique [0002] Existing computers transmit and process information electronically. With the advancement of semiconductor process technology, the size of transistors is getting smaller and smaller, and the number of transistors that can be integrated on a chip is increasing. When the CPU obtains a higher main frequency, the power consumption rises sharply, and the leakage and heat dissipation problems cannot be solved. . From the perspective of the development of high-speed computers, the use of electrons as transport information carriers can no longer meet people's requirements for faster processing speeds of computers, which shows that the ability to improve the computing speed of existing computers is ...

AI Technical Summary

Problems solved by technology

[0004] Computer operations are all binary number calculations, and the existing traditional non-reversible logic devices are mainly non-reversible logic gates with two inputs and one output. When the input information passes through the gate, one output information bit will be lost. As early as 1960, R.Landauer proposed It has been proved that every operation of irreversible computing will cause the loss of bits, and every time a bit of information is lost, kTln2 heat energy will be dissipated. Although the energy loss is very small at room temperature, it cannot be ignored for the design of low-power devices

At the same time, the heat generated by energy consumption will greatly limit the performance and computing speed of the chip
