High-speed Fading-free Direct Detection for DoubleSideband OFDM Signal via Block-wise Phase Switching
High-speed Fading-free Direct Detection Double Sideband OFDM Signal Block-wise Phase Switching
2014/11/6
We employ phase switching of either main-carrier or subcarriers of two consecutive signal blocks for double-sideband fading-free direct-detection (DD). In so doing, 40-Gb/s DDOOFDM is successfully rec...

Present-day networks are being challenged by dramatic increases in bandwidth demand of emerging applications. We will explore a new transport, ”optical flow switching”, that will enable significant gr...
Homing Architectures in Multi-Layer Networks:Quantifying the Effect of ODU Switching
Fiber Optics network optimization protection and restoration
2015/6/5
Alternative homing architectures can lead to significant cost reductions. Using linear programming we quantify these reductions for IPoWDM and IPoOTN networks under a multi-layer consideration for a r...
We propose a scalable optical switching architecture towards contention-free interconnection for data center networks. The simulations show it can support higher load and throughput with significantly...
This work proposes an adaptive routing scheme based on ant optimization techniques and novel graph-based waveband assignment algorithm to accommodate and group online lightpath requests while minimizi...
We investigate the feasibility of a 1x4096 optical-packet-switch (OPS) operating at 160Gb/s, by cascading two 1x64 OPSs in a fat-tree configuration. We find error-free operation with 5.7dB penalty ove...
