Design and research of high-order mode generation based on asymmetric dual-core optical fiber
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 (LP<sub>11</sub>, LP<sub>21</sub>, LP<sub>02</sub>). Taking the ADCF with a small core diameter of 8 μm as an example, the operating bandwidth (coupling efficiency in excess of 95% (LP<sub>11</sub>) and 90% (LP<sub>21</sub>, LP<sub>02</sub>)) is 202nm, 54nm, and 60nm, respectively.
