Asymmetric nonlinear-mode-conversion in an optical waveguide with PT symmetry
Changdong Chen, Youwen Liu, Lina Zhao +2
Asymmetric mode transformation in waveguide is of great significance for on-chip integrated devices with one-way effect, while it is challenging to achieve asymmetric nonlinear-mod…
Ultra-bright multiplexed energy-time entangled photon generation from lithium niobate on insulator chip
Guang-Tai Xue, Yun-Fei Niu, Xiaoyue Liu +14
High-flux entangled photon source is the key resource for quantum optical study and application. Here it is realized in a lithium niobate on isolator (LNOI) chip, with 2.79*10^11 H…
Generations of high efficiency, high purity, and broadband Laguerre-Gaussian modes from a Janus optical parametric oscillator
Dunzhao Wei, Pengcheng Chen, Xiaopeng Hu +7
Laguerre-Gaussian (LG) modes, carrying orbital angular momentum of light, are critical for important applications such as high-capacity optical communications, super-resolution ima…
Drone-based all-weather entanglement distribution
Hua-Ying Liu, Xiao-Hui Tian, Changsheng Gu +13
The quantum satellite is a cornerstone towards practical free-space quantum network and overcomes the photon loss over large distance. However, challenges still exist including rea…
Generating controllable Laguerre-Gaussian laser modes through intracavity spin-orbital angular momentum conversion of light
Dunzhao Wei, Yue Cheng, Rui Ni +4
The rapid developments in orbital-angular-momentum-carrying Laguerre-Gaussian (LG0 l) modes in recent years have facilitated progresses in optical communication, micromanipulation…
Coupled orbital angular momentum conversions in a quasi-periodically poled LiTaO3 crystal
Xinyuan Fang, Guang Yang, Dunzhao Wei +8
We experimentally demonstrate the orbital angular momentum (OAM) conversion by the coupled nonlinear optical processes in a quasi-periodically poled LiTaO3 crystal. In such crystal…
Diffraction Interference Induced Superfocusing in Nonlinear Talbot Effect
Dongmei Liu, Yong Zhang, Jianming Wen +6
We report a simple, novel sub-diffraction method, i.e. diffraction interference induced super-focusing in second-harmonic (SH) Talbot effect, to achieve focusing size of less than…
Wave-front engineering by Huygens-Fresnel principle for nonlinear optical interactions in domain engineered structures
Yi-qiang Qin, Chao Zhang, Yong-yuan Zhu
The wave-front engineering for nonlinear optical interactions was discussed. Using Huygens-Fresnel principle we developed a general theory and technique for domain engineering with…
