Hi Jesuwanth_Sugesh
Sorry that due to the restriction, we cannot open any files attached here. This looks to be a problem that the ring modulator doesn't work well for 1553 nm operating wavelength. COuld you pelase try the same file for 1550 nm for the CWL and confirm that you can see the eye properly? Then if you can see an open eye for 1550 nm operating wavelength, it confirms that the model is not optimized for 1553 nm. You may want ot tune the ring modulator model to make it work better under 1553 nm.
