I build a ring modulator in INTERCONNECT, inside it I import several mode waveguides, the properties of mode waveguide come from Mode Solutions. The schematic is shown below.

 

Then I test the gain with different wavelength under scattering data mode in ONA, the result is normal

 

But for impulse response mode for ONA, the corresponding gain distribution is very strange as shown below

 

 

Could you please help me find the problem? Thank you and wish your reply

Hi WENKAI YANG,

Thank you for the post. You will need to set some properties in the waveguides and couplers. Please refer to this page the "Important model settings" section: https://optics.ansys.com/hc/en-us/articles/360042329094-Ring-modulator-time-domain-INTERCONNECT-. Here are also some settings and explanations on the time domain setting and verification:

I got it!

Thanks a lot~
