To simulate the spectrum of QDs, I&#8217;ve set a small number on wavelength span and disabled the short pulse optimization . But as the picture shows, the FDTD results are unusable. How can I set a dipole source with narrow FWHM correctly or fix the FDTD outputs?<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/18-02-2024-1708283423-mceclip0.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/18-02-2024-1708283665-mceclip1.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/18-02-2024-1708283674-mceclip2.png\"><\/p>\n","protected":false},"template":"","class_list":["post-352186","topic","type-topic","status-closed","hentry","topic-tag-dipole","topic-tag-fdtd","topic-tag-source-setting-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["59397","33648"],"_bbp_author_ip":["23.52.43.81"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["275"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["352186"],"_bbp_forum_id":["27833"],"_bbp_engagement":["33648","59397"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["352908"],"_bbp_last_active_id":["352908"],"_bbp_last_active_time":["2024-02-21 17:44:53"]},"test":"lined7792gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/352186","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\/352186\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=352186"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
