We report the results of an experimental investigation of inter-modal nonlinearities in a 4.7-km few-mode fiber (FMF).

The rate of erosion and polymerization of methane ice under bombardment by hydrogen and helium ions is studied in the laboratory as a function of ion energy and ice film thickness.

We report on experimental investigations of real-time maximum-likelihood sequence estimation (MLSE) in the presence of narrowband optical filtering, using 10.7-Gb/s nonreturn-to-zero ON-OFF keying

We report on experimental investigations of real-time maximum likelihood sequence estimation (MLSE) in the presence of narrow-band optical filtering, using 10.7-Gb/s non return-to-zero on-off keyin

We study the effect of optical filter concatenation on a 42.

We demonstrate application of polarization-switched-QPSK subcarrier modulation together with soft-FEC LDPC coding and iterative demapping on OFDM lab system.

The spherical inertial-electrostatic confinement (SIEC) concept is designed to focus and accelerate ions and electrons radially inward towards the center of a negatively biased, highly transparent

We implemented a transmitter with variable symbolrate (up to 64Gbd) and constellation (up to 64QAM) und study experimentally the linear and nonlinear performance and the maximum transmission reach

We show experimentally that the nonlinear transmission performance of Nyquist-filtered 128- Gb/s PDM-QPSK and 256-Gb/s PDM-16QAM signals is direction-dependent in inhomogeneous fiber links.

Measurements of SOA with various optical confinements show that low confinement devices are not saturated by ASE.
