Topological edge states and disorder robustness in one-dimensional off-diagonal mosaic lattices
Ba Phi Nguyen, Kihong Kim
We investigate topological edge states in one-dimensional off-diagonal mosaic lattices, where nearest-neighbor hopping amplitudes are modulated periodically with period . Anal…
Statistical regimes of electromagnetic wave propagation in randomly time-varying media
Seulong Kim, Kihong Kim
Wave propagation in time-varying media enables unique control of energy transport by breaking energy conservation through temporal modulation. Among the resulting phenomena, tempor…
Deterministic time rewinding of waves in time-varying media
Seulong Kim, Kihong Kim
Temporal modulation of material parameters offers unprecedented control over wave dynamics, enabling phenomena beyond the capabilities of static systems. Here we introduce and anal…
Scaling behavior of the localization length for TE waves at critical incidence on short-range correlated stratified random media
Seulong Kim, Kihong Kim
We theoretically investigate the scaling behavior of the localization length for -polarized electromagnetic waves incident at a critical angle on stratified random media with sh…
Investigation of variation in fluorescence intensity from rhodamine 6G Dye
S. M. Iftiquar, H. Zilay
Variation in fluorescence intensity from rhodamine 6G dye was investigated. A small volume of dye solution was optically excited with a 0.4 mW, 532nm wavelength cw-laser light. The…
Microsphere-coupled light emission control of van der Waals heterostructures
Hyunseung Lee, Van Tu Nguyen, Ji-Yong Park +1
Two-dimensional transition metal dichalcogenides (TMDCs) integrated to photonic structures provide an intriguing playground for the development of novel optoelectronic devices with…
