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

We report on the fabrication and optimization of lithium niobate planar and ridge waveguides at the wavelength of 633 nm.To obtain a planar waveguide,oxygen ions with an energy of 3.0 MeV and a fluence of 1.5×1015 ions/cm2 are implanted in the polished fa
Our previous work had proved pump field noise coupling in the seed field injected optical parametric amplifier[OPA]at a certain analysis frequency.Inspired by this noise coupling mechanism,the frequency dependent squeezing factor due to excess pump noise
Lithium niobate on insulator[LNOI],as an emerging and promising optical integration platform,faces shortages of on-chip active devices including lasers and amplifiers.Here,we report the fabrication of on-chip erbium-doped LNOI waveguide amplifiers based o
Topological photonics provides a new opportunity for the examination of novel topological properties of matter,in which the energy band theory and ideas in topology are utilized to manipulate the propagation of photons.Since the discovery of topological i
Built-in piezoelectric field improved photocatalytic performance of nanoflower-like Bi2WO6 using low
Photocatalysis technology has been proved to be a potential strategy for removal of organic dyes, however high-power light sources are generally necessary to initiate photocatalytic reaction. In this work, we employed an excellent photocatalyst of Bi2WO6
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
Designed preparation of CoS/Co/MoC nanoparticles incorporated in N and S dual-doped porous carbon na
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
