• This letter discusses the characteristics of orbital angular momentum (OAM) of hybrid mode in the cylindrical corrugated waveguide. The well-known discussion of the OAM in Laguerre-Gaussian (L-G) laser fields is applied to the hybrid mode of the corrugated waveguide. The analytical discussions of the OAM are also investigated by numerical simulations of the finite-difference time-domain (FDTD) method. It is found that the hybrid modes in the corrugated waveguide carry well-defined OAM.
