Transverse magnetic field of waveguide is also simulated in Lumerical Mode. Calculated values are \(n_{eff}\)=1.7691(TM0) and \(n_g\)=3.7481(TM0). Field profile is mostly in normal direction to the wafer, and considering the edge roughness of waveguide as the primary reason of scattering loss, in TM mode loss is much more lower compared to TE mode. Loss is 3x10-4dB/cm.
