I got that dimension size from analytical calculation (V-number method). Does Lumerical have a better (simulative) way to calculate it?nI need to know (or see) the number of mods propagating in order to compare it to the analytical calculation (single mode).nHow can I see the propagating mods inside the Silicon Nitride layer itselft, and not at the whole structure? How do I need to setup the Eigenmode solver parameters? I would appreciate if you could explain it in as much details as you can, I pretty new to the software and having trouble understanding how to setup the simulations specific to what I need\u2026nI attached my preliminary design in a sketch, it has more dimension sizes so you could understand the \u201cbigger picture\u201d. Could you maybe help me build it or explain to me how to? also, in the design there is a binary grating, it is only an initial structure, and the main goal is that the grating will be more customized one, more like a cut sinus profile, or dome-like lines. Could it be design in Lumerical?n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/BVVUQSRTU3U8\/image.png\" width=\"718\" height=\"603\" \/>nThanks again for all your help.n<\/p>\n","protected":false},"template":"","class_list":["post-53312","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["25628"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["A\u014aE"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["713"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["53312"],"_bbp_forum_id":["27833"],"_bbp_engagement":["185544"],"_bbp_voice_count":["1"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["146216"],"_bbp_last_active_id":["146216"],"_bbp_last_active_time":["2021-03-13 01:23:24"]},"test":"gwang"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/53312","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/53312\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=53312"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
