Emulating exceptional-point encirclements using imperfect (leaky) photonic components
J. B. Khurgin, Y. Sebbag, E. Edrei +4
Non-Hermitian systems have recently attracted significant attention in photonics. One of the hallmarks of these systems is the possibility of realizing asymmetric mode switching an…
Fast and slow nonlinearities in ENZ materials
Jacob B. Khurgin, Matteo Clerici, Nathaniel Kinsey
Novel materials, with enhanced light-matter interaction capabilities, play an essential role in achieving the lofty goals of nonlinear optics. Recently, Epsilon-Near-Zero (ENZ) med…
Absorptive loss and band non-parabolicity as a physical origin of large nonlinearity in epsilon-near-zero materials
Ray Secondo, Jacob B. Khurgin, Nathaniel Kinsey
For decades, nonlinear optics has been used to control the frequency and propagation of light in unique ways enabling a wide range of applications such as ultrafast lasing, sub-wav…
