Error-Free 320 Gb/s Simultaneous Add-Drop Multiplexing
H. C. Hansen Mulvad,Leif Katsuo Oxenløwe,A.T. Clausen,Michael Galili,L. Gruner-Nielsen,Palle Jeppesen +5 more
TL;DR: In this article, the first demonstration of error-free time-division add-drop multiplexing at 320 Gb/s was presented in a non-linear optical loop mirror with only 100 m of highly nonlinear fiber.
Proceedings ArticleDOI
Optical waveform sampling of a 320 Gbit/s serial data signal using a hydrogenated amorphous silicon waveguide
Hua Ji,Hao Hu,Minhao Pu,Michael Galili,Palle Jeppesen,Bart Kuyken,Shankar Kumar Selvaraja,Geert Morthier,Roel Baets,Leif Katsuo Oxenløwe +9 more
TL;DR: In this article, a hydrogenated amorphous silicon waveguide was proposed for ultra-high-speed serial data waveform sampling. But the authors only used a single waveguide with +12 dB intrinsic four wave mixing conversion efficiency.

4-Dimensional Quantum Key Distribution Protocol over 52-km Deployed Multicore Fibre
Mujtaba Zahidy,Domenico Ribezzo,Chiara De Lazzari,Ilaria Vagniluca,Nicola Biagi,T. Occhipinti,Leif Katsuo Oxenløwe,Michael Galili,Tetsuya Hayashi,S. Antonelli,Antonio Mecozzi,Alessandro Zavatta,Davide Bacco +12 more
TL;DR: In this paper , the authors demonstrate a 4D path-encoded QKD system over a 52-km multi-core fieldinstalled fiber network, which has a 68.5 kbit/s secret key rate.
Proceedings Article
Characterization of a Wavelength Converter for 256-QAM Signals Based on an AlGaAs-On-Insulator Nano-waveguide
Francesco Da Ros,Metodi P. Yankov,Edson Porto da Silva,Minhao Pu,Luisa Ottaviano,Hao Hu,Elizaveta Semenova,Soren Forchhammer,Darko Zibar,Michael Galili,Kresten Yvind,Leif Katsuo Oxenløwe +11 more
TL;DR: In this article, a 9mm AlGaAs-On-Insulator waveguide is shown to provide high-quality (OSNR > 30 dB) idler generation over a 28-nm bandwidth enabling error-free conversion of 10-GBd 256-QAM with OSNR penalty below 2.5 dB.
Proceedings ArticleDOI
All-optical ultra-high-speed OFDM to Nyquist-WDM conversion
Pengyu Guan,Kasper Meldgaard Roge,H. C. Hansen Mulvad,Michael Galili,Hao Hu,Toshio Morioka,Leif Katsuo Oxenløwe +6 more
TL;DR: An all-optical ultra-high-speed OFDM to Nyquist-WDM conversion scheme based on complete OFT is proposed with BER <; 10-9 performance for all channels.
