Proceedings ArticleDOI
A semiconductor laser amplifier in a loop mirror as a phase comparator in PLL-based clock recovery for 160 Gb/s data signals
TL;DR: In this article, a semiconductor laser amplifier in a loop mirror was investigated for clock recovery from 160 Gb/s data signals, and a width of the switching window larger than the bit period was appropriate.
Proceedings ArticleDOI
Broadband and efficient dual-pump four-wave-mixing in AlGaAs-on-insulator nano-waveguides
Francesco Da Ros,Minhao Pu,Luisa Ottaviano,Hao Hu,Elizaveta Semenova,Michael Galili,Kresten Yvind,Leif Katsuo Oxenløwe +7 more
TL;DR: In this article, dual-pump four-wave mixing in AlGaAs-on-insulator nano-waveguides was shown to achieve an output conversion efficiency as high as −8.5 dB at 155mW pump power.
Journal ArticleDOI
Synchronization in a Random Length Ring Network for SDN-Controlled Optical TDM Switching
Valerija Kamchevska,Valentina Cristofori,Francesco Da Ros,Bingli Guo,Christopher L. Jackson,Anna Manolova Fagertun,Sarah Ruepp,Reza Nejabati,Dimitra Simeonidou,Lars Dittmann,Michael Stübert Berger,Leif Katsuo Oxenløwe,Michael Galili +12 more
TL;DR: A novel synchronization algorithm is proposed that enables automatic synchronization of software defined networking controlled all-optical TDM switching nodes connected in a ring network and can facilitate dynamic slot size change and failure detection.
Proceedings ArticleDOI
160 Gb/s silicon all-optical data modulator based on cross phase modulation
Hao Hu,Minhao Pu,H. Ji,Michael Galili,H. C. Hansen Mulvad,Kresten Yvind,Jørn Märcher Hvam,Palle Jeppesen,Leif Katsuo Oxenløwe +8 more
TL;DR: In this article, the extinction ratio of 18.5 dB was achieved for the optically modulated 160 Gb/s signal in a silicon nanowire-based all-optical data modulation system.
Proceedings ArticleDOI
Characterisation of systems for raman-assisted high-speed wavelength conversion
Michael Galili,Leif Katsuo Oxenløwe,Darko Zibar,Anders Clausen,Palle Jeppesen,Hans-Jürgen Deyerl,Nikolai Plougmann,Martin Kristensen +7 more
TL;DR: In this article, Ramaman assisted wavelength conversion for ultra-high speed data is characterised in approaches: a novel scheme based on cross-phase modulation using specially designed notch filters and a 160 Gb/s experiment based on self phase modulation.
