Using a newly developed long-period grating filter to improve the timing tolerance of a 320 Gb/s demultiplexer
Leif Katsuo Oxenløwe,Michael Galili,H. C. Hansen Mulvad,Palle Jeppesen,Radan Slavik,José Azaña,Yongwoo Park +6 more
TL;DR: A 0.8 ps flat top pulse was generated using a long-period fiber grating and used as control pulse for the first time in a 320 Gb/s demultiplexer as mentioned in this paper.
Proceedings ArticleDOI
Silicon waveguide based 320 Gbit/s optical sampling
Hua Ji,Michael Galili,Minhao Pu,Liu Liu,Leif Katsuo Oxenløwe,Palle Jeppesen,T. Veng,Lars Gruner-Nielsen +7 more
TL;DR: In this paper, a silicon waveguide-based ultra-fast optical sampling system is successfully demonstrated using a free-running fiber laser with a carbon nanotube-based mode-locker as the sampling source.
Proceedings ArticleDOI
Noise Statistics and its Implications on Optimal Constellation Shapes for Channels with Optical Phase Conjugation
Henrik Enggaard Hansen,Metodi P. Yankov,Pawel M. Kaminski,Francesco Da Ros,Leif Katsuo Oxenløwe,Soren Forchhammer +5 more
TL;DR: Probabilistic shaping designed for AWGN channels used on dispersion-compensated channels with mid-link OPC results in shaping gains comparable to those of specialized shaping.
Proceedings ArticleDOI
Terabit/s serial optical communications (invited)
TL;DR: This work reports on an experimental demonstration of a 1.28 Tbit/s serial data generation and demultiplexing and discusses the prospects of upgrading other essential functionalities to 1.
Proceedings ArticleDOI
Nonlinearity Compensation through Optical Phase Conjugation for Improved Transmission Reach/Rate
Francesco Da Ros,Metodi P. Yankov,Edson Porto da Silva,Mads Lillieholm,Pawel M. Kaminski,Pengyu Guan,Hao Hu,Anders T. Clausen,Michael Galili,Leif Katsuo Oxenløwe +9 more
TL;DR: This work reviews the recent investigations on the impact of sub-optimum transmission links as well as the effort on the implementation of the optical phase conjugator itself looking beyond using highly nonlinear fibers as nonlinear medium and focusing on integrated silicon waveguides.
