Using the quantum interference of photon pairs in N-stage nonlinear interferometers[NLIs],the contour of the joint spec-tral function can be modified into an islands pattern.We perform two series of experiments.One is that all of the nonlinear fibers in p
We propose and demonstrate a polarization diversity two-dimensional grating coupler based on the lithium niobate on insulator platform,for the first time,to the best of our knowledge.The optimization design,performance characteristics,and fabrication tole
A novel thin-film lithium niobate[TFLN]electro-optic modulator is proposed and demonstrated.LiNb03-silica hybrid wave-guide is adopted to maintain low optical loss for an electrode spacing as narrow as 3 pm,resulting in a low half-wave-voltage length prod
High-Q lithium niobate[LN]optical micro-resonators are an excellent platform for future applications in optical commu-nications,nonlinear optics,and quantum optics.To date,high-Q factors are typically achieved in LN using either dielectric masks or femtos

The development of low-cost and highly efficient bifunctional electrocatalysts toward oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is of critical importance for clean energy devices such as fuel cells and metal-air batteries. Herein
The nonlinear Talbot effect is a near-field nonlinear diffraction phenomenon in which the self-imaging of periodic objects is formed by the second harmonics of the incident laser beam.We demonstrate the first,to the best of our knowledge,exam-ple of nonli
Yolk-shell nanostructural Ni2P/C composites as the high performance electrocatalysts toward urea oxi
Highly active and low-cost catalytic electrodes for urea oxidation reaction (UOR) are always crucial for exploration of urea fuel cells. Herein, novel york-shell-structural Ni2P/C nanosphere hybrids (Ni2P/C-YS) are rationally constructed via a hydrotherma
Periodically poled lithium niobate on insulator[LNOI]ridge waveguides are desirable for high-efficiency nonlinear frequency conversions,and the fabrication process of such waveguides is crucial for device performance.In this work,we report fabrication and
We demonstrate a three-nanosecond equidistant sub-pulse multi-step Q-switched Nd∶Y3Al5O12[Nd∶YAG]laser.In the time interval of 100-1000 ns,three pulses with the same nanosecond interval and the same peak power are obtained at the pulse width of 24 ns,28 n
A millimeter-sized negatively charged polymer embedded with molybdenum disulfide nanosheets for effi
Molybdenum disulfide (MoS2) has excellent trapping ability for lead ions whereas its micro-/nanoscale size has greatly impeded its practical applications in the flow-through systems. Herein, a millimeter-sized nanocomposite MoS2-001 was synthesized for Pb
