Non-Hermitian Linear Electro-Optic Effect Through Interactions of Free and Bound Charges
Sylvain Lannebère, Nader Engheta, Mário G. Silveirinha
In recent years, there has been growing interest in non-Hermitian phenomena in low-symmetry conductors, particularly optical gain driven by electro-optic effects. Conventional semi…
Electrically Tunable Excitonic-Hyperbolicity in Chirality-Pure Carbon Nanotubes
Jason Lynch, Pavel Shapturenka, Mohammad Mojtaba Sadafi +8
Metamaterials exhibiting hyperbolic dispersion enable unprecedented control over light-matter interactions, from sub-diffraction imaging to enhanced spontaneous emission. However,…
Gain-Momentum Locking in Chiral-Gain Media
João C. Serra, Nader Engheta, Mário G. Silveirinha
Conventional optical materials are characterized by either a dissipative response, which results in polarization-independent absorption, or by a gain response that leads to wave am…
Natural Hyperbolicity of Hexagonal Boron Nitride in the Deep Ultraviolet
Bongjun Choi, Jason Lynch, Wangleong Chen +6
Hyperbolic media enable unique optical phenomena including hyperlensing, negative refraction, enhanced photonic density of states (PDOS), and highly confined polaritons. While most…
