Changsha kiln was an ancient factory from the Tang Dynasty (618–907 CE) to the Five Dynasties (907–960 CE), famous for its colored porcelain production. It was one of the pioneer sites to master the poly-color technique at high temperature. In this work, by using Energy Dispersive X-Ray Fluorescence (EDXRF), Raman spectroscopy and Scanning Electron Microscopy Energy Dispersive X-ray Spectrometer (SEM-EDS),...
We demonstrate a flexible multi-dimensional modulation method for elastic optical networks. We compare the flexible multi-dimensional modulation formats PM-kSC-mQAM with traditional modulation formats PM-mQAM using numerical simulations in back-to-back and wavelength division multiplexed (WDM) transmission (50GHz-spaced) scenarios at the same symbol rate of 32Gbaud. The simulation results show that...
We demonstrate 1.2 Tb/s single span real-time transmission over 4 types of fiber with PDM-QPSK Nyquist WDM prototype systems. Performance of different fiber is compared and 332km transmission over ULL is achieved without inline amplification.
We demonstrate a 1.2 Tb/s real-time transmission over 4 types of optical fiber with 120G PDM-QPSK Nyquist WDM prototype systems. Performance of different fiber is compared and 3200km transmission is achieved without Raman amplification.
