Dear All, I am a beginner in COMSOL thermo-optic field. I want to calculate the change in temperature in a waveguide. I created a waveguide structure having a rectangular core and cladding with heater as a heat source just above the cladding surface. After the simulation, I found some temperature gradient over the structure.
Now my question is, how can I calculate temperature and change in temperature in the core (waveguide) area?
Thank you! The version is Comsol 5.4.
