Abstract
We design and demonstrate a high-order mode (HOM) convertor based on asymmetric dual-core fiber (ADCF) with high coupling efficiency, wide bandwidth and high stability. The two ends of the ADCF are fused with single-mode fiber and few-mode fiber respectively. A periodic power transfer in the ADCF, thereby achieving direct mode conversion from the fundamental mode to HOMs (LP11, LP21, LP02). Taking the ADCF with a small core diameter of 8 μm as an example, the operating bandwidth (coupling efficiency in excess of 95% (LP11) and 90% (LP21, LP02)) is 202nm, 54nm, and 60nm, respectively.
