Problems solved by technology

[0004] However, the current optical adder is mainly based on the principle of nonlinear optics, which requires a beam of high-intensity laser as the pump light when the optical adder is working. The working conditions are extremely harsh and difficult to achieve.
What is more fatal is that the optical adder based on the principle of nonlinear optics is not compatible with the current CMOS process in terms of manufacturing process, and large-scale production is difficult

Abstract

The invention discloses a microring resonator based binary optical full adder which comprises three microring resonators of different structures and five Y-shaped branch-line couplers, is input with three electrical pulse sequences to be calculated and outputs optical pulse sequences after calculation with an addition with a carry flag. The binary optical full adder is completely compatible with aCMOS technology, so that the microring resonator based binary optical full adder is small in size, low in power consumption, rapid in speed, good in extensibility and convenient in integration and play an important role in a photon computer.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a binary optical full adder based on a microring resonator. Background technique [0002] With the development of semiconductor technology, the density of multi-processors on the chip is increasing, and the integration of monolithic integrated circuits is getting higher and higher. On this basis, the CPU of the computer has a higher main frequency, which greatly improves The computing speed of the computer. The improvement of the computer's main frequency has brought many problems, the biggest problem is the sharp increase of power consumption, followed by heat dissipation and leakage problems. It is obvious that it is difficult to develop along the route stipulated by Moore's Law just according to this development model. In response to this problem, scientists began to look for computers based on new physical mechanisms, including photonic computers and quantum com...
