Abstract
The cutoff frequencies of guided modes in a dielectric optical tube waveguide are derived under a condition of the weak guidance. It is shown that the order of mode is significantly different from that of a conventional singly clad fiber especially when a thickness of the tube becomes thin.Keywords
