Hi all, I am trying to do optical simulation of a simple structure comprising of Si and SiO2 in sdevice. Everything seems to work except for the fact that while visualizing the plots of parameters such as Optical Intensity, I am not seeing any raytracing in the oxide layers. Although light is propagating on to the subsequent silicon layer along the propagation direction, the oxide in between is not populated with the rays in SVisual plot, which is expected. Is there anything I should include in the code to turn on optical raytracing in the oxide ? Any help? Although Sentaurus is taking the right index and extinction values for oxide in the simulation. I checked it.
