Optical fiber sensor has been widely used in many areas due to its intrinsicadvantsges such as lightweight, compact size.high sensitivities, immunity to electromagnetic interference, corrosion resistance, and so on.Regarding to configuration, fiber sensors can usually be classified into two categories: point sensors and distributed sensors.Distributed fiber sensors are usually achieved by using Rayleigh. Raman or Brillouin scattering, while point sensors are constructed based on fiber gratings, all sorts of interferometers and other short-length-interaction effects by moons of various post-processing techniques.Recently, a new processing method.i.e..twisting optical fibers into helical shapes, attracts increasing attention due to the unique properties of helical-sfructured fibers.Such special structure fibers have been demonstrated great potentials for both communication and sensing applications.In this talc, we will introduce some of our rear works on helical -structured mu Moore fiber based sensors.By using C02 laser processing system, we fabricated different types of helical -structured multicore fibers (HSMCFs) and then
constructed HSMCFs based sensors with different configurations fa temperature, strain and torsion measurement.

The boundary element method (BEM).together with the finite element method (FEM) and the finite difference method (FDM), constitute three basic numerical methods.Because the boundary element method only calculates the function values of the nodes on the boundary, it has the advantages of reducing dimension and less degrees of freedom of solution.After calculating the function values of the nodes on the boundary by the boundary element method, the function values in the field can be further calculated.However, the coefficient matrix formed by BEM is full, which requires high computer memory, thus restricting the degree of freedom of solution.In order to improve the accuracy of boundary element calculation without increasing the degree of freedom.the methods of improving the accuracy of boundary element calculation are introduced from the aspects of singular integral analytical method of linear triangular element, regular surface boundary element and general surface boundary element.

IPS Seminar on "Ultrafast mode-locked and quantum frequency combs: controlling the optical phase in mesoscopic architectures"
Recent advances in sub-wavelength nanosale platforms have afforded the control of light from first principles, with impact to ultrafast sciences, optoelectronic and precision measurements.In this talk I will highlight two examples where emerging microscale architectures can make a dfference.First, he described recent advances in chip-scale Kerr frequency comb oscillators, where we have achieved sub-100-fs pulse mode-locking, one of the shortest pulse Kerr comb to date.Coherent mode-locking is observed in the normal dispersion regime, verified by phase-resolved ultrafast spectroscopy at sub-100-attojoule sensitivities.Soiton mode-locking and crystals, graphene-controlled optical frequency combs, and coherent THz sources will be discussed.
Second, he described our studies on quantum entanglement for dense secure communications, based on high-dimensional biphoton frequency combs.Working with time-and frequency-bins, we demonstrate quantum revival of Hong-Ou-Mandel second-order correlation of the qubits.Long postulated by theorists more than a decadeago, we experimentally demonstrate up to 19 dimensions and with visibifities up to 96.5%.The phase-locked high-dimensional qudit state is further witnessed through two non-local stabilized interferometers-in a Frans on-type configuration -as a generalized Bell's inequafity test of hyperentanglement through multiple degrees-of-freedom. Entanglement revivals of the non-local interference at discrete time-bins are uncovered for the first time, up to 97.8% visibility, as a fundamental resource for dense secure information processing.

Nowadays,health and environmental issues become two major challenges, which strongly influence the health and the social behaviour of people over the world. Thus, there is an urgent need for the development of efficient diagnosis tools in order to act on this alarming problem that threatens public health. Particularly, by offering highly sensitive detection methods in order to monitor air quality or enable reliable detection diseases at the early stages.This presentation reports the using Of carbon,polymer and bio organisms as sensitive materials based acoustic，microwave and optical platforms for sensing in a gaseous and a liquid medium and valid ation of a quantitative,non- invasive diagnosis tooI.

Olympics sport and the most recognizable format of our modern archery. Shooting archery is a pastime nearly anyone can partake in. Men, women and children are able to stretch a string and send an arrow towards its target. Archery offers a physical and mental challenge to all who bend a bow. Like most sports, hobbies or pastimes,technology has invaded the realm of archery. Necessary hand eye coordination has been diminished by the institution of mechanical releases and accurate sight
