Dual bound states in the continuum in metamaterials
Longqing Cong, Ranjan Singh
Bound state in the continuum (BIC) is a mathematical concept with an infinite radiative quality factor (Q) that exists only in an ideal infinite array. It was first proposed in qua…
Electrically programmable chiral MEMS photonics
Longqing Cong, Prakash Pitchappa, Nan Wang +1
Optical chirality is central to many industrial photonic technologies including enantiomer identification, ellipsometry-based tomography and spin multiplexing in optical communicat…
All-dielectric active photonics driven by bound states in the continuum
Song Han, Longqing Cong, Yogesh Kumar Srivastava +6
Recently emerged dielectric resonators and metasurfaces offer a low-loss platform for efficient manipulation of electromagnetic waves from microwave to visible. Such flat meta-opti…
Metamaterial analogue of Ising model
Longqing Cong, Vassili Savinov, Yogesh Kumar Srivastava +2
The interaction between microscopic particles has always been a fascinating and intriguing area of science. Direct interrogation of such interactions is often difficult or impossib…
Tailoring the slow light behavior in terahertz metasurfaces
Manukumara Manjappa, Sher-Yi Chiam, Longqing Cong +3
We experimentally study the effect of near field coupling on the transmission of light in terahertz metasurfaces, possessing slightly distinctive SRR resonances. Our results show t…
