In this paper, we proposed a point-to-multipoint fiber-optic time transfer scheme over ring networks. The proposed scheme is experimentally demonstrated over a 400 km ring fiber network with the communication data transmission in an adjacent channel. The results show that the clock difference with the mean value of less than 9.4 ps is obtained, and the time stability in terms of time deviation can be better than 15.17 ps@1s, while the bit error rate of the communication data transmission is better than $1.37\times 10^{-14}$ .

Generation of hyperentangled photon pairs is investigated based on the lithium niobate straight *** propose to use the nonlinear optical process of spontaneous parametric down-conversion(SPDC)and a well-designed lithium niobate waveguide structure to generate a hyperentangled(in the polarization dimension and the energy-time dimension)two-photon *** performing numerical simulations of the waveguide structure and calculating the possible polarization states,joint spectral amplitudes(JSA),and joint temporal amplitudes(JTA)of the generated photon pair,we show that the generated photon pair is indeed hyperentangled in both the polarization dimension and the energy-time dimension.
A Multi-Resolution Integration Method for the demodulation of non-uniform strain is proposed, which can solve the low correlation issues associated with non-uniform strain distribution in small-bandwidth optical refle...
