Quasi-bandgap behavior in non-Hermitian photonic crystals

Jin Xu, Daniel Cui, Aaswath P. Raman

We investigate non-Hermitian photonic crystals in which the lossy and lossless constituents share the same real permittivity and differ only in their imaginary part. We characteriz…

Magneto-optic perturbation theory for near-complete violation of Kirchhoff's law of thermal emission at low magnetic fields

Daniel Cui, Aaswath P. Raman

Magneto-optic photonic systems can violate Kirchhoff's law of thermal emission by breaking Lorentz reciprocity. We develop a dispersive perturbation theory yielding an analytical e…
