R. Ryf,Rene-Jean Essiambre,Alan H. Gnauck,Sebastian Randel,M. A. Mestre,Christian Schmidt,Peter J. Winzer,R. Delbue,Peter J. Pupalaikis,A. Sureka,Tetsuya Hayashi,Toshiki Taru,Takashi Sasaki +12 more
TL;DR: In this article, the authors demonstrate multiple-input-multiple-output transmission of a combined 3-space-, and 2-polarization-, and 5-wavelength-division multiplex in a 3-core microstructured fiber over 4200 km.
Proceedings ArticleDOI
Mode-multiplexed 6×20-GBd QPSK transmission over 1200-km DGD-compensated few-mode fiber
Sebastian Randel,R. Ryf,Alan H. Gnauck,M. A. Mestre,Christian Schmidt,Rene-Jean Essiambre,Peter J. Winzer,R. Delbue,Peter J. Pupalaikis,A. Sureka,Yi Sun,Xinli Jiang,Robert Lingle +12 more
TL;DR: In this paper, low differential group delay (DGD) between the modes of a graded-index few-mode fiber is obtained by combining segments with DGD of opposite sign.
Journal ArticleDOI
Comparison of interferometric all-optical switches for demultiplexing applications in high-speed OTDM systems
Colja Schubert,J. Berger,Stefan Diez,H.J. Ehrke,Reinhold Ludwig,U. Feiste,Christian Schmidt,H.G. Weber,G. Toptchiyski,Sebastian Randel,Klaus Petermann +10 more
TL;DR: In this paper, three interferometric all-optical switches based on cross-phase modulation (XPM) in SOAs, the semiconductor laser amplifier in a loop mirror (SLALOM) switch, and the ultrafast nonlinear interferometer (UNI) switch are compared and their application is discussed as demultiplexer in optical time division multiplexing (OTDM) systems for data rates of 40, 80, and 160 Gb/s.
Journal ArticleDOI
Phase dynamics of semiconductor optical amplifiers at 10-40 GHz
TL;DR: In this article, the phase dynamics that occur in bulk InGaAsP-InP semiconductor optical amplifiers (SOAs) in response to picosecond pulse excitations at 10 and 40 GHz are studied experimentally and numerically for various amplifier lengths.
Proceedings ArticleDOI
160 Gbit/s optical 3R-regenerator in a fiber transmission experiment
S. Watanabe,Fumio Futami,Ryou Okabe,Yutaka Takita,S. Ferber,Reinhold Ludwig,Colja Schubert,Christian Schmidt,H.G. Weber +8 more
TL;DR: In this paper, a fiber-based, wavelength-shift free 3R-regenerating repeater was operated at 160 Gbit/s in a dispersion-managed fiber link for the first time.
