Spaser in Coupled Metamaterials: The gain effect in a magnetic plasmon waveguide
S. M. Wang, Z. H. Zhu, J. X. Cao +4
Loss is a crucial problem in plasmonic integrated optical circuits and metamaterials. The Er, Yb codoped gain material is introduced into a magnetic plasmon waveguide composed of a…
Modeling the directed transmission and reflection enhancements of the lasing spaser in active metamaterials
Z. G. Dong, H. Liu, T. Li +5
Simultaneously enhanced reflectance and transmittance greater than 35 dB are demonstrated for the lasing spaser (or spasing) behavior in an active fishnet metamaterial. In mimickin…
Suppression of radiation loss by hybridization effect in two coupled split-ring resonators
T. Q. Li, H. Liu, T. Li +6
This paper investigates the radiation properties of two coupled split-ring resonators (SRRs). Due to electromagnetic coupling, two hybrid magnetic plasmon modes were induced in the…
Optical loss compensation in a bulk left-handed metamaterial by the gain in quantum dots
Zheng-Gao Dong, Hui Liu, Tao Li +5
A bulk left-handed metamaterial with fishnet structure is investigated to show the optical loss compensation via surface plasmon amplification, with the assistance of a Gaussian ga…
Coupled magnetic plasmons in metamaterials
H. Liu, Y. M. Liu, T. Li +3
Magnetic metamaterials consist of magnetic resonators smaller in size than their excitation wavelengths. Their unique electromagnetic properties were characterized by the effective…
Structural-configurated magnetic plasmon bands in connected ring chains
T. Li, R. X. Ye, C. Li +5
Magnetic resonance coupling between connected split ring resonators (SRRs) and magnetic plasmon (MP) excitations in the connected SRR chains were theoretically studied. By changing…
