Five channel optical waveguides are investigated numerically by using mode-matching method. The precise numerical results of the dispersion relations near the cutoff and the field distributions are presented for the lowest five HE modes. When the geometric parameters of the waveguides can be optimized so as to satisfy the phase-matching condition, it is shown that the five channel optical waveguides operate as power divider.
