Strategy for designing broadband epsilon-near-zero metamaterial with loss compensation by gain media
Lei Sun, Kin Wah Yu
A strategy is proposed to design the broadband gain-doped epsilon-near-zero (GENZ) metamaterial. Based on the Milton representation of effective permittivity, the strategy starts i…
Integrated optical devices based on broadband epsilon-near-zero meta-atoms
Lei Sun, Kin Wah Yu, Xiaodong Yang
We verify the feasibility of the proposed theoretical strategy for designing the broadband near-zero permittivity (ENZ) metamaterial at optical frequency range with numerical simul…
Photonic Bloch-dipole-Zener Oscillations in Binary Parabolic Optical Waveguide Arrays
Ming Jie Zheng, Yun San Chan, Kin Wah Yu
We have studied the propagation and Zener tunneling of light in the binary parabolic optical waveguide array (BPOWA), which consists of two evanescently coupled dissimilar optical…
Harmonic oscillations and their switching in elliptical optical waveguide arrays
Ming Jie Zheng, Yun San Chan, Kin Wah Yu
We have studied harmonic oscillations in an elliptical optical waveguide array in which the coupling between neighboring waveguides is varied in accord with a Kac matrix so that th…
Tunable Hybridization at Mid Zone and Anomalous Bloch-Zener Oscillations in Optical Waveguide Ladders
Ming Jie Zheng, Gang Wang, Kin Wah Yu
We have studied the optical oscillation and tunneling of light waves in optical waveguide ladders formed by two coupled planar optical waveguide arrays. For the band structure, a m…
Steering between Bloch oscillation and dipole oscillation in parabolic optical waveguide arrays
Ming Jie Zheng, Yun San Chan, Kin Wah Yu
We study the optical oscillations of supermodes in planar optical waveguide arrays with parabolically graded propagation constant in individual waveguide interacting through neares…
