We propose and experimentally demonstrate an efficient equalization-enhanced phase noise compensation scheme for long-haul coherent transmission. The distance is extended by 1780km and 470km for $\mathbf{788.4}-\mathbf{Gb}/\mathbf{s}/\boldsymbol{\lambda}$ and 968.4- $\mathbf{Gb}/\mathbf{s}/\boldsymbol{\lambda}$ line rate WDM transmission, respectively, using 3-MHz LO and receiver-side dispersion compensation.
Double second-order sideband with suppressed carrier modulation technology is developed for OFDR system. With an equivalent frequency sweeping range of 80GHz, spatial resolution of 1.083mm over 2km fiber is realized w...

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...
