Polarization entanglement enabled by orthogonally stacked van der Waals NbOCl2 crystals
Qiangbing Guo, Yun-Kun Wu, Di Zhang +5
Polarization entanglement holds significant importance for photonic quantum technologies. Recently emerging subwavelength nonlinear quantum light sources, e.g., GaP and LiNbO3 thin…
Beam shaping by nonlinear moiré metasurfaces
Lun Qu, Wei Wu, Di Zhang +7
This paper explores the interplay of momentum transfer and nonlinear optical processes through moiré phenomena. Momentum transfer plays a crucial role in the interaction between ph…
Bright Second Harmonic Emission from Photonic Crystal Vertical Cavity
Lun Qu, Zhidong Gu, Chenyang Li +12
We present a study on photonic vertical cavities consisting of nonlinear materials embedded in photonic crystals (PhCs) for resonantly enhancing second harmonic generation (SHG). P…
Infrared full-Stokes polarimetry by parametric up-conversion
Zhanghang Zhu, Di Zhang, Fei Xie +7
Polarimetry aims to measure polarization information of an optical field, providing a new freedom to enhance performance of optical metrology. Furthermore, the polarimetry in infra…
