<p> <\/p><p>Dear Amrita,<\/p><p>thank you very much for your answer! I will definitely read the article you sent me and implement the example that you linked!<\/p><p>Just as a additional info, I set the interfaces with this command: <\/p><p> <\/p><p>“set(“interface absolute positions”, [0, h_wg, h_wg+t]);”<\/strong><\/p><p> <\/p><p>where h_wh = 1.3613 um and t = 0.1 um and automatically I got the interfaces set as in the picture I attached.<\/p><p>To confirm also the result, I calculated the refractive index distribution and I was able to see all the three indices of the three layers (actually about that I’ve seen that there is a bug in the visualization of the cross section because the thicknesses of the layers do not match the actual values but in FDTD there is no such a problem. However I’ve seen on another post on the forum that this is actually a visual bug that does not interfere with the simulation results).<\/p><p>Also, is there a difference in results between defining the interfaces between “reference positions” and absolute positions”? Because I find more intuitive defining them in terms of “absolute positions”.<\/p><p>Thank you in advance<\/p><p>Regards<\/p><p> <\/p><p>Giovanni<\/p><p> <\/p><p> <\/p><p> <\/p><\/p>\n","protected":false},"template":"","class_list":["post-373543","reply","type-reply","status-publish","hentry"],"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
