摘要
We show stable modes (stationary self-trapped beams) of elliptic cross section in an elliptic-core nonlinear fiber. These stable modes can be tapered in the presence of absorption or gain. Ellipticity of the beam can be controlled by induced tapering. Another interesting feature is the possibility of conversion of an elliptic Gaussian laser beam into a circular Gaussian laser beam. A stationary self-trapped beam plus an elliptic-core nonlinear fiber form an elliptic-core Linear fiber for a low-power signal beam, and hence one can induce an elliptic-core linear fiber of optically tunable parameters for a low-power signal beam.
