Broad-angle photon-pair generation from flatband quasi-BIC resonant 3R-MoS metasurfaces
Tingting Liu, Huifu Qiu, Xintong Shi +2
Spontaneous parametric down-conversion (SPDC) in ultrathin optical resonant metasurfaces offers a promising platform for integrated quantum light sources. However, conventional res…
Coexistence and manipulation of multiple singularities in a reconfigurable non-Hermitian metasurface
Xintong Shi, Yanjie Wu, Rui Zhou +6
Non-Hermitian frameworks extend conventional Hermitian physics, offering a powerful paradigm for describing open systems. Central to this field are various singularities within the…
Doubly resonant nonlinear metasurfaces enabling NIR-to-UV upconversion for reconfigurable Fourier optical processing
Jumin Qiu, Meibao Qin, Tingting Liu +6
Fourier optical processing underpins optical information manipulation, yet extending such operations to short wavelengths within compact platforms remains challenging. Here, we add…
Super-robust telecommunications enabled by topological half-supermodes
Rui Zhou, Xintong Shi, Hai Lin +6
Topological photonics offers transformative potential for robust integrated waveguide devices due to their backscattering-immune properties. However, their integration faces two fu…
Polarization-controlled non-Hermitian metasurfaces for ultra-sensitive terahertz sensing
Xintong Shi, Hai Lin, Tingting Liu +8
Non-Hermitian systems offer significant advantages in sensor design, especially at the exceptional points. However, the extreme sensitivity near these points poses great challenges…
