The burst control packet (BCP) process time in the OBS core node is very important for the OBS networks. Although several OBS testbeds have been reported, the BCP process time in core node is still not fast enough. In...

A system is proposed to use BP neural network and Fresnel transform technique for computer-generated hologram compression. In experiments, this scheme is more robust and effective than DCT and DWT compression under lo...

We propose two inter-carrier interference (ICI) self-cancellation schemes based on CO-OFDM system. They can not only enhance the laser linewidth tolerance of the system, but also improve the robustness against fiber n...

We demonstrated the superluminal propagation at negative group velocity using stimulated Brillouin scattering (SBS) in optical fibers. In the scheme, the Stokes wave is circulated back into the ring cavity for Brillouin lasing to enhance the peak loss. The experiment demonstrated the superluminal light propagation can be realized by increasing the input signal power. The largest time advancement of 221.2ns has been observed. Correspondingly, the negative group velocity is -0.15c and the group index is -6.636.

We propose and experimentally demonstrate a simple and cost-effective scheme to converge a 60-GHz radio-over-fiber (RoF) system with a wavelength division multiplexed-passive optical network (WDN-PON) system. Only 10-GHz electronic devices are used to generate a 60-GHz RoF signal based on frequency-sextupling technology. For n-channel WDN-PON and RoF converged system, only n+1 modulators are required.
This paper investigates the "Blind Zone" of electronic packet header processing in the core routers of asynchronous optical packet switching network. Simulation shows that the "Blind Zone" has sign...

For real-time massive data aggregations, we propose a WDM backbone-access network and design an integrated OADMOLT interface node to realize all-optical connections between the backbone and the access networks. Under such a network infrastructure, we formulate a Light-path-Assignment and Time-Scheduling (LATS) problem for the massive data aggregation application. We prove this problem to be NPcomplete and develop a heuristic approach based on problem decomposition. Extensive simulations demonstrate the effectiveness and the feasibility of the proposed approach.
We propose and experimentally demonstrate a simple and cost-effective bi-directional radio-over-fiber (RoF) system for simultaneous transmission of downstream baseband, microwave (MW) and millimetre-wave (MMW) signals...
