Description
Summary:In this paper, the LP<sub>11</sub> mode evolution in a few mode-polarization maintaining fiber is experimentally investigated. Selective conversion from the LP<sub>11a</sub>/LP<sub>11b</sub> mode to the LP<sub>11b</sub>/LP<sub>11a </sub>, OAM<sub>&#x002B;1</sub>, and OAM<sub>&#x2212;1</sub> modes are demonstrated with varying wavelengths and fiber lengths. This property may have nice applications in spatial division multiplexing (SDM) systems, and one of them, i.e., the all-fiber compact and robust scalar orbital angular momentum (OAM) generator, which is cascaded by a mode-selective coupler and a few mode-polarization maintaining fiber, is also demonstrated with expected performance for conversion between LP<sub>01</sub> mode and OAM<sub>&#x002B;1</sub>/OAM<sub>&#x2212;1</sub>.
