If the taper cone angle is large, you may try varFDTD and 3D FDTD:Ĭurved waveguide taper (varFDTD and FDTD)Īs for how large the angle is large, it depends. Polarization converter using a tapered waveguide Thank you.ĭid you run 'emepropagate'? I tested and there is no any issue showing yz profile:įor common taper with small cone angle, EME is perfect to design and optimize, Here are some examples: I will then calculate the overlap between the taper mode and a fiber mode.
but only need an accurate mode profile at the narrow tip of the taper. lms file? I am using Lumerical through a university license.Īlso, what is the best approach (EME/varFDTD/FDTD?) if I want to simulate the output only of an adiabatic waveguide taper with sub-wavelength features? I am not optimizing the taper length, etc. lms files so I have attached a screenshot of the new YZ monitor settings. Will you please let me know what I am doing wrong here? This forum does not allow me to upload. I have added a new monitor (cross_section_mode_monitor) and disabled the existing one (Field_profile) accordingly, but when I run the simulation, no results are loading into the new monitor and I cannot visualize the YZ field. Hi, I am following this linear taper example ( ) but I would like to add a mode field monitor to visualize the YZ mode (X-normal) instead of the XY mode (Z-normal).
