Journal ArticleDOI
Error-free all-optical wavelength conversion at 160 gb/s using a semiconductor optical amplifier and an optical bandpass filter
Y Yong Liu,Eduward Tangdiongga,Z. Li,S. Zhang,Huug de Waardt,GD Giok-Djan Khoe,H.J.S. Dorren +6 more
TL;DR: In this paper, an error-free and pattern-independent wavelength conversion at 160 Gb/s was demonstrated using an optical bandpass filter (OBF) placed at the amplifier output.
Journal ArticleDOI
All-optical network subsystems using integrated SOA-based optical gates and flip-flops for label-swapped networks
E. Kehayas,Jorge Seoane,Yongzhi Liu,José Manuel Guaita Martínez,Javier Herrera,P.V. Holm-Nielsen,S. Zhang,R. McDougall,Graeme Maxwell,Francisco Ramos,Javier Martí,H.J.S. Dorren,Palle Jeppesen,Hercules Avramopoulos +13 more
TL;DR: In this paper, the authors demonstrate that all-optical network subsystems, offering intelligence in the optical layer, can be constructed by functional integration of integrated alloptical logic gates and flip-flops.
Journal ArticleDOI
Ring-laser optical flip-flop memory with single active element
TL;DR: In this article, a flip-flop configuration with two unidirectional ring lasers with separate cavities but sharing the same active element is presented, where light in the lasing cavity can suppress lasing in the other cavity so that this system forms an optical bistable element.
Journal ArticleDOI
40-Gb/s All-Optical Processing Systems Using Hybrid Photonic Integration Technology
E. Kehayas,Dimitris Tsiokos,Paraskevas Bakopoulos,Dimitrios Apostolopoulos,D. Petrantonakis,L. Stampoulidis,Alistair James Poustie,R. McDougall,Graeme Maxwell,Yong Liu,S. Zhang,H.J.S. Dorren,Jorge Seoane,P. Van Holm-Nielsen,Palle Jeppesen,Hercules Avramopoulos +15 more
TL;DR: In this paper, an experimental performance characterization of all-optical subsystems at 40 Gb/s using interconnected hybrid integrated optical amplifier (SOA) Mach-Zehnder interferometer (MZI) gates and flip-flop prototypes is presented.
Proceedings ArticleDOI
Optical shift register based on an optical flip-flop memory with a single active element
S. Zhang,Z. Li,Y Yong Liu,R. Geldenhuys,Heongkyu Ju,Daan Lenstra,GD Giok-Djan Khoe,J.S. Dorren +7 more
TL;DR: An optical shift register that consist out of two serially connected optical flip-flop memories driven by common clock pulses, which makes the optical flips easily cascade with each other.
