<p>Hello,<br><br>I am working on an inverse-designed 2×2 3-dB SWG-based power splitter using Lumopt, aiming for equal power split between the bar and cross ports. To achieve this, I set the figure of merits (FOMs) to 0.5 for each port and used two separate FOM monitors (fom1 and fom2) to track the power distribution. However, I consistently observe that the FOM at the bar port exceeds that at the cross port, leading to an imbalance.<\/p><p>Could you advise on whether it’s possible to introduce an additional FOM or constraint to minimize this mismatch? Any guidance on adjusting the optimization setup to achieve a more balanced output would be greatly appreciated.<\/p><p>Thank you very much for your assistance.<\/p><p>-Partha<br><br>\"\"<\/p><p>\"\"<\/p><\/p>\n","protected":false},"template":"","class_list":["post-392441","topic","type-topic","status-publish","hentry","topic-tag-inverse-design-2","topic-tag-photonics","topic-tag-subwavelength-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
