If so, I would try to avoid the planar projection if so as I need to simulate the mode expansion between 1 and 10 um from the facet.&lt;\/p&gt;&lt;p&gt;I tried your suggested example &#8220;Facet-reflection-and-transmission-calculations&#8221; and works well for what I need. My aim is to calculate the power coupling between two waveguides at a specific distance from each other. The example is really useful to calculate the mode distribution of one of the waveguides after a distance but how can I check its power coupling with the other one? I could use a full 3D-FDTD simulation with mode expansion monitors but I would prefer to use an overlap analysis as quick test before a long simulation as final one. I noted that FDTD has the overlap function between two monitor modes, is there a function to find the best position for coupling such as &#8220;optimizeposition&#8221;?&lt;\/p&gt;&lt;p&gt;Alternatively, I was wondering whether I can export the mode from a monitor in zbf format and load it in the d-card of the FDE overlap analysis tab. It seems possible but does not recognise the overlap.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-365280","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/365280","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/365280\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=365280"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
