All-Optical 160-Gbit/s Retiming System Using Fiber Grating Based Pulse Shaping Technology
Francesca Parmigiani,Leif Katsuo Oxenløwe,Michael Galili,Morten Ibsen,Darko Zibar,Periklis Petropoulos,David J. Richardson,Anders Clausen,Palle Jeppesen +8 more
TL;DR: In this article, a retiming system operating at rates of 40 and 160 Gbit/s, which incorporates a superstructured fiber Bragg grating (SSFBG) as a pulse shaping element, is presented.
Journal ArticleDOI
Experimental demonstration of the DPTS QKD protocol over a 170 km fiber link
Beatrice Da Lio,Davide Bacco,Daniele Cozzolino,Yunhong Ding,Kjeld Dalgaard,Karsten Rottwitt,Leif Katsuo Oxenløwe +6 more
TL;DR: In this paper, the authors present the experimental demonstration of the differential phase-time shifting protocol (DPTS) up to 170 km of fiber link and compare its performance with coherent one-way (COW) and differential phase shifting (DPS) protocols, demonstrating a higher secret key rate up to 100 km.
Journal ArticleDOI
300 Gb/s IM/DD based SDM-WDM-PON with laserless ONUs.
TL;DR: A low-cost, high-speed SDM-WDM-PON architecture is proposed by using a multi-core fiber and intensity modulation/directly detection (IM/DD) and low inter-core crosstalk of a MCF, increasing the aggregated capacity and avoiding the Rayleigh backscattering noise.
Journal ArticleDOI
Optical wavelength conversion of high bandwidth phase-encoded signals in a high FOM 50cm CMOS compatible waveguide
Francesco Da Ros,Edson Porto da Silva,Darko Zibar,Sai T. Chu,Brent E. Little,Roberto Morandotti,Michael Galili,David J. Moss,Leif Katsuo Oxenløwe +8 more
TL;DR: In this paper, the authors demonstrate wavelength conversion of QAM signals including 32GBd QPSK and 10GBd 16QAM in a 50cm long high index doped glass spiral waveguide.
Combined Optical and Electrical Spectrum Shaping for High-Baud-Rate Nyquist-WDM
Edson Porto da Silva,Robert Borkowski,Fabian Schwartau,Simone Gaiarin,Miguel Iglesias Olmedo,Armand Vedadi,Molly Piels,Michael Galili,Pengyu Guan,Sergei Popov,Camille-Sophie Brès,Thomas Schneider,Leif Katsuo Oxenløwe,Darko Zibar +13 more
TL;DR: In this article, the benefits and limitations of optical time-division multiplexing (OTDM) techniques based on the optical generation of a periodic train of sinc pulses for WDM transmission at high baud rates are discussed.
