Broadband generation of multiple high-order OAM modes in ring-core fibers using multi-pitch chirped long-period fiber gratings

A multi-order broadband mode converter in a ring-core fiber (RCF) using a multi-pitch chirped long-period fiber grating (LPFG), where multiple pitches were introduced in each chirp to further increase the bandwidth, is proposed and demonstrated. The grating parameters were optimized both theoretical...
