✦ Synopsis

Figure 5 Comparisons between our results obtained using CMM w x and Tefiku, Yamashita, and Funada's 4 results derived using rectan-Ž . gular-division method for the coupling coefficient a and the mode velocity ratio when h s h 2 so the dielectric overlays can be used for lowering or compensating the large mode velocity ratio. Moreover, the accuracy of the closed-form expressions has been confirmed by comparison with results from the rectangular-division method.
