Hi, I encountered some problems when studying S-parameters in INTERCONNECT as follows:<\/p>\n

I use “s-parameter sweep” in “Optimizations and Sweep” to get the S-parameter of the 4×4 MMI.<\/p>\n

<\/p>\n

After get the S-parameter, I put it into “Optical N port S parameter” in INTERCONNCT and take a test simulation like the follows:<\/p>\n

<\/p>\n

After check the power of the OOSC_1-4, I found the power is different with the “S-parameter data file”(Get from the MODE), not only that, the transmittance obtained by varFDTD simulation in the same MODE file is also different from the value recorded in the S-parameter data file. This has caused confusion to me. Can you please explain it to me?<\/p>\n

<\/p>\n

<\/p>\n

Wish you have a good day, thanks a lot \ud83d\ude42<\/p>\n","protected":false},"template":"","class_list":["post-315178","topic","type-topic","status-closed","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\n\t\t\n\t\t\n\t\t
