标题: Multi-Ring-Core Chalcogenide Fiber Supporting >4000 OAM Modes Across C+L Bands
摘要: 
Multiplexing, known as transmitting multiple signals such as time, wavelength, polarization, or space into one physical channel, is a technology for increasing the overall data-carrying capacity and efficiency. In recent years, space has been considered as the next dimension to overcome the capacity crunch of the current optical communication systems based on single-mode fibers (SMFs).

Orbital angular momentum (OAM) mode, which has the unique helical phase front and theoretically infinite topological charge value l, could be used as a different dimension to create an additional set of data carriers in optical transmission system. The complex multiplexing schemes of combining mode division multiplexing (MDM) technology based on OAM modes with dense space-division multiplexing (DSDM) in multi-core fibers (MCFs) can be utilized to further improve the data rate and spectral efficiency.

In this talk, we introduce a multi-OAM multi-ring air-core fiber, which has 37 high-index rings with each ring supporting 112 radially fundamental OAM modes across C and L bands from 1530 nm to 1625 nm, i.e. 4144 OAM modes in total. Moreover, the designed fiber features <-49 dB crosstalk at 1550 nm and <-20 dB crosstalk across C and L bands after 100-km fiber propagation.
