This Demonstration graphs core intensity profiles for the linearly polarized modes in a single-step index optical fiber. These modes are of particular interest because there is no degeneracy in the propagation constant between different mode orders, and they are particularly easy to identify due to their linear polarization in the transverse plane. The profiles have the form of cylindrical Bessel functions of integer order.
