Problems solved by technology

[0003] Computer operations are binary number calculations, and the existing traditional calculation methods are based on non-reversible logic devices. One bit of information will be lost. According to the Landauer principle, every operation of irreversible calculation will cause the loss of bits, and every bit of information lost will have kTln2 heat energy dissipated

Abstract

The invention provides a reversible optical exclusive or logic device based on microring resonators. The reversible optical exclusive or logic device consists of two microring resonators and a Y-shaped branch coupler, two electrical pulse sequence inputs to be calculated and optical pulse train outputs subjected to exclusive or calculation; the inputs and the outputs are in one-to-one correspondence. A manufacturing process of the reversible optical exclusive or logic device provided by the invention is completely compatible with a COMS (Complementary Metal Oxide Semiconductor) process, so that the device is small in size, quick in speed, low in power consumption and convenient for integration, and is expected to play an important role in photon computers.

Description

technical field [0001] The invention belongs to the field of optical logic computing, and relates to a reversible optical logic device based on a microring resonator, in particular to a reversible XOR optical logic device based on a microring resonator suitable for the fields of optical communication and optical computing. Background technique [0002] With the continuous development of semiconductor technology, the integration of chips or integrated circuits is getting higher and higher, and the size of integrated components is further reduced. The leakage and heat dissipation problems of traditional electrical devices cannot be well solved. There are more and more signs that optical information processing and optical computing have very bright prospects as a solution to replace traditional electrical information processing. The parallelism of optical signal transmission makes the optical system have a wider information channel than the electrical system; the integrated opt...
