Roughness-induced radiation losses in optical micro or nanofibers (MNFs) are investigated using an induced-current model. Loss coefficients of silica, phosphate, tellurite and silicon MNFs with sinusoidal deformations on their surfaces are numerically calculated with respect to typical parameters of the guiding system. Interesting phenomena such as the existence of the loss minima at specific perturbation periods are observed. Results presented in this work may be generalized to all kinds of surface deformation and may provide useful guidelines for both estimating and tailoring waveguiding properties of MNFs.
