Abstract: We have proposed an effective method of generating the first-order orbital angular momentum (OAM) modes in ring fibers. The first-order OAM modes (L = &x00B1;1) can be represented as the linear superposition of the HE<sub>21</sub><sup>even</sup> mode and the HE<sub>21</sub><sup>odd</sup> mode. Through exerting pressure on the ring fiber by a leverage device, the fundamental mode HE<sub>11</sub> can be coupled into higher order mode HE<sub>21</sub>in broadband wavelength ranging from 1530 to 1600 nm. By adjusting the fiber polarization controller and the pressure value exerted on the fiber, both the positive (L = +1) and negative (L = - 1) OAM modes can be generated separately. Moreover, we have demonstrated that the coupling efficiency from the fundamental mode to the first-order OAM modes at wavelength of 1550 nm can reach 67%.
