How can photonic-crystal slab modes and light–matter coupling be computed efficiently?
Expands fields in guided modes and adds symmetry, radiation and excitonic coupling treatments.
Supports differentiable design and compares results with RCWA.
Relation labels come from the method guide and are editorial. Unlabelled links are conceptual connections or comparison methods; the paper does not necessarily implement them.
CONNECTIONS
GEOMETRY & MODES
Can a large or unusual cavity emit into a useful collective mode?
STRONG COUPLING
What emerges when the material excitation and photon become hybrid modes?
COMPUTATION
Can we optimize the optical behaviour we actually need?
READ ALONGSIDE IT
Combines a perovskite excitonic medium with a moiré photonic landscape.
Patterns a GaAs/InGaAs microcavity and combines polarization-resolved measurements with modal and rate-equation models.
Unifies Fourier-modal and dynamical-diffraction ideas with polygonal profile descriptions.
Commentary
The basis and radiative-loss approximations need convergence checks, especially outside weak-leakage regimes.
Useful when the central question is band dispersion or modal loss rather than driven diffraction.
