Summary
Can emission from many independent dipoles be cheap enough to optimize a micro-LED?
Uses vector FMM, shared linear algebra, Brillouin-zone integration and automatic differentiation.
Demonstrates light-extraction optimization and comparison with FDTD.

Commentary
The large reported speedup concerns a particular many-dipole workload. It is not a universal FMM/FDTD ratio.
Localized-source integration complements thick-layer decoherence; the two solve different coherence problems.
