Accurate forms for the generalized LP1m mode in a uniform circular-core curved fiber are given. We show that each generalized LP1m mode is composed of four linearly polarized partial fields. We also show that, when the propagation constants of HE2m, TM0m, and TE0m modes are degenerate, there are four linearly polarized modes for each generalized LP1m mode.
