✦ Synopsis
tion range. This situation can be interesting for dispersion shift design.
Ž . Ž . Ž . 3. Considering profile 2 in Figure 4 a and b , if now the Ž . minimum -level rises, profile 3 is defined, and the associated dispersion falls, presenting a much wider and lower valued stationary peak.
Ž . Ž . Ž . 4. Except for case 1 of Figure 4 a , b associated with a high third medium -level, the maximum values for stationary peaks are higher when linear profiles are considered.
Conclusions
Considering extended and double-extended W-and M-type profiles, it was concluded that the waveguide dispersion patterns associated with each group are very different. In general, for the W-types, the dispersion characteristics are strongly dependent on the index levels, and a peak may occur, inside or beyond the single-mode frequency range. In general, it is higher valued for linear profiles. For M-type profiles, dispersion curves are, in general, flatter, and the maximum attained values are much lower than those associated with W-types.
