A new designed dual-guided ring-core fiber for OAM mode transmission
A new designed dual-guided ring-core fiber for SDM transmission is proposed. The ring region support OAM mode and the core region hold the fundamental mode across the whole C band. Fiber features such as dispersion, differential mode delay, effective mode area, power isolation and modal birefringence have been analyzed comprehensively.
