The fast parallel restoration (FPR) scheme is proposed to achieve the fast setup of restoration label switched path (LSP) in the distributed optical networks. The scheme is derived by dividing the whole restoration LSP into several segments of sub-LSP and
We demonstrate a visible light communication system based on DC-biased optical orthogonal frequency-division multiplexing (DCO-OFDM) and achieve a bit rate of 481 Mb/s at a communication distance of 65 cm by employing single 1-W commercial phosphorescent
We report a diode-end-pumped Q-switched YVO4/Nd:YVO4/YVO4 self-Raman second-Stokes laser at the wavelength of 1764 nm. With the incident pump power of 32 W and the pulse repetition frequency of 20 kHz, the maximal average output power at 1764 nm is up to
