Spectral expansions of open and dispersive optical systems: Gaussian regularization and convergence

Spectral expansions of open and dispersive optical systems: Gaussian regularization and convergence

Resonant states (RS), also known as quasi-normal modes, arise in spectral expansions of linear response functions of open systems. Manipulation of these spatially ‘divergent’ oscillating functions requires a departure from the usual definitions of inner product, normalization and orthogonality typic...
