2010/6/5
We propose and demonstrate a spectral phase and amplitude modulator spanning full 2D-space by crossing a 100GHz WGR and a 1200gr/mm bulk grating. We address individual WDM channels with high resolutio...
Deployment analysis of TDM/WDM Single Fiber PON with Colourless ONU Operating at 2.5 Gbps Subcarrier Multiplexed Downstream and 1.25 Gbps Upstream
Optical communications Optical networks
2010/6/5
A single-fiber full-duplex hybrid TDM/WDM-PON is demonstrated to operate at 2.5/1.25 Gbps rates, with RSOA ONU. It achieves high power budget (GPON compliant) at a distances higher than 20km, and serv...

Optical communications Phase modulation
2010/6/4
We implement a cost efficient 10.7Gb/s directly modulated DPSK transmitter in a bidirectional WDM-PON, which also remodulates the downstream phase encoded signal for 2.5Gb/s OOK upstream transmission.
Nonlinear Penalty Reduction Induced by PMD in 112 Gbit/s WDM PDM-QPSK Coherent Systems
Nonlinear Penalty PMD WDM PDM-QPSK Coherent Systems
2009/7/20
We show by simulation that when linear PMD is fully compensated by the receiver, the presence of DGD along the link reduces the amount of residual nonlinear penalty in 112 Gbit/s PDM-QPSK coherent sys...

Dispersion Management WDM Coherent PDM-QPSK Systems
2009/7/20
We show that dispersion management with DCF does not outperform electronic dispersion compensation for WDM coherent NRZ-PDM-QPSK systems, but for time-interleaved RZ-PDM-QPSK systems,dispersion manage...
