I’m using FDTD to simulate mode distribution in hexagonal nanowire (NW) (axial GaAs quantum well between axial GaAsP barriers) and use Mode source alingned with NW to model QW emission.
If I check properties (Edit object) of the Source and then choose “User Selected” and then “Calculate modes” around max n (refractive index), it shows me 20 modes - but doesn’t identify them.
Of coursem I can look at field distribution and guess, but I’d prefer FDTD to indentify modes for me (e.g., mode 1 = TE01, mode 2= TM01, mode = HE31 etc.).
WIll the Mode expansion monitor do the job? If it will - where to place it? If not - how else this can be done to identify modes?
P.S. Apologies if my question is too naive, I’m a newbie to FDTD.
