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…
Flat optics for analog computing: from fundamental mechanisms to advanced meta-processors
Tingting Liu, Jumin Qiu, Xintong Shi +2
As the explosive growth of visual data increasingly strains the latency and energy limits of conventional electronic computing, optical analog computing has re-emerged as a disrupt…
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…
Wavefront Control and Intensity Modulation of Third Harmonic Generation in Nonlocal Metasurfaces
