✦ Synopsis
Using Goell's point-matching method under the weak guidance condition, modal characteristic equations ha¨e been deri¨ed for two lightguides with double con¨ex lens-shaped core cross sections. In one case, both of the boundaries are taken as conducting, and in the other case, we consider only one side as conducting. In both cases, dispersion cur¨es are obtained and compared.
