Abstract

The invention discloses a reconfigurable mode converter based on a Mach-Zehnder interferometer, which comprises a third-order mode demultiplexer and a third-order mode multiplexer connected with each other. The third-order mode demultiplexer and the third-order mode multiplexer are both connected with a Mach-Zehnder interferometer switch group; the demultiplexer is used for demultiplexing the multimode waveguide, the Mach-Zehnder switch is used for controlling mode output, and the multiplexer is used for multiplexing modes in the Mach-Zehnder switch into the multimode waveguide. According to the reconfigurable mode converter, a scheme is provided for flexible conversion between different modes in a mode multiplexing technology in optical communication, and the problem of efficient utilization of the device area caused by increasing scale of an optical information network is effectively solved. The device can be highly integrated, is compact in structure, is good in reconfigurability, and can play an important role in the application of the optical interconnection network.

Description

technical field [0001] The invention belongs to the technical field of optical information processing, and relates to an optical information processing device, in particular to a reconfigurable mode converter based on a Mach-Zehnder interferometer. Background technique [0002] With the development of Internet technology and applications in the information age, people have higher and higher requirements for large-capacity and high-speed data communications. In order to meet the needs of the data age, wavelength division multiplexing technology in high-speed optical transmission of various structures has been studied. However, the growth rate of communication capacity and communication rate is increasing day by day, and the wavelength division multiplexing technology can no longer meet the demand of exponentially increasing data volume. Therefore, researchers have proposed various other types of multiplexing techniques to improve communication capacity. As another dimension...
