Elevator coupler¶

examples/fdtdx_elevator_coupler.py simulates an adiabatic coupler between two SiN tapers on different levels: TE0 at 619 nm is launched into the upper taper, and the script sweeps the taper overlap. examples/meep_elevator_coupler.py runs the same structure in MEEP, and examples/compare_elevator_coupler.py plots the two together:
