There would appear to be some discrepancy between what you have sent me and where you got those results from. Either that or you are using a much older version of the product. I ran your design and at 1550 nm um while it does not propagate across the resonator as seen in yours it is certainly well confined (see 1550nm.PNG). The worst results I could get from your simulation were for 1682 nm which is outside the bandgap you are using so it is not surprising (see 1682nm.PNG).

Is the design you sent in fact the same one you used to get those results? Note that the one you sent did not have an observation area covering the whole XZ space as shown in your results so some changes were made.

It also looks like the colour scale is saturated. Can you include a version of that result with the colour bar so I can see the scale?
