Ultra low loss Hollow-core Anti-resonant fiber for multiplexing communication with cylindrical vector beams

摘要

Traditional quartz optical fibers can not overcome their own shortcomings in non-linearity, Rayleigh scattering, dispersion and high delay~([1,2]),while anti-resonant hollow fibers can break through Shannon limit, and have the characteristics of low loss, low delay, high bandwidth and high damage threshold. With the development of new technologies such as Internet of Things and large data, people's increasing demand for information and traditional reuse. Ways including wavelength division multiplexing, frequency division multiplexing and space division multiplexing have gradually encountered bottlenecks ~([3]). We need to explore new ways of multiplexing, improve the information capacity of communication networks, and meet the growing information needs of people. Through research we find a new type of cylindrical vector beams, which is not only the spatial orthogonal mode, but also the basis of optical fibers. The signature mode can improve the communication capacity of the channel.
