We review recent advances in understanding Kerr nonlinear limitations in high-capacity long-haul coherent systems, with emphasis on PDM-QPSK transmissions. Both homogeneous and hybrid dispersion-manag...
Channel estimation for a reduced-guard-interval (RGI) CO-OFDM system shows a unique dependence on the training symbol design in the presence of intra-channel nonlinearities.Because smaller FFT sizes c...
We investigate the use of an enhanced backpropagation algorithm where subbanding and frequency-shaping by pre- and post-filters are used in the calculation of nonlinearity to enable larger step sizes ...
We model fiber parametric entangled photon sources for use in quantum key distribution applications. Effects of Raman scattered photons are evaluated and are found to be manageable when appropriately ...
Technologies for fiber nonlinearity management for spectrally-efficient high-speed optical transmission systems have been discussed from a carrier perspective. While optimal electrical dispersion mana...
We propose DFT-spread (DFT-S) OFDM within each sub-band of multiband-CO-OFDM to mitigate fiber nonlinearity. For 1000-km standard-single-mode-fiber transmission at 420-Gb/s, 32-band DFT-S CO-OFDM outp...
Feasibility toward tera-sample/s all-optical ADC using NOLM and its promising applicationssuch as front-end processor of EDC for above 100Gbit/s optical transmission systems are discussed. Recent reco...
We consider Active Constellation Extension to reduce the PAPR in CO-OFDM systems. We find that the nonlinearity threshold is improved by 1.5 dB at a reach of 400 km SSMF fiber.
