OAM modes characteristics analysis and low-loss transmission based on topological confinement
Yifan He, Xuchen Hua, Lei Shen +4
The topological confinement is a new mechanism that allows the transmission of cutoff orbital angular momentum (OAM) modes with negligible loss in ring-core fibers (RCFs) and provi…

Efficient Raman Frequency Conversion by Feedbacks of Pump and Stokes Fields
Bing Chen, Kai Zhang, Chun-Hua Yuan +5
We experimentally demonstrate efficient Raman conversion to respective Stokes and anti-Stokes fields in both pulsed and continuous modes with a Rb-87 atomic vapor cell. The convers…
