1.28 Tbit/s single-polarisation serial OOK optical data generation and demultiplexing
Hans Christian Hansen Mulvad,Leif Katsuo Oxenløwe,Michael Galili,A.T. Clausen,Lars Gruner-Nielsen,Palle Jeppesen +5 more
TL;DR: A 1.28 Tbaud data signal is demonstrated, which is the highest symbol rate yet reported, and is demultiplexed in a nonlinear optical loop mirror, resulting in error-free performance with a BER < 10 -9 for all 128 demultipalxed channels.
Journal ArticleDOI
Fano resonance control in a photonic crystal structure and its application to ultrafast switching
Yi Yu,Mikkel Heuck,Hao Hu,Weiqi Xue,Christophe Peucheret,Yaohui Chen,Leif Katsuo Oxenløwe,Kresten Yvind,Jesper Mørk +8 more
TL;DR: In this paper, a photonic crystal structure that allows easy and robust control of the Fano spectrum is presented, which relies on controlling the amplitude of light propagating along one of the light paths in the structure from which the resonance is obtained, and demonstrates its advantages by the experimental realization of 10 Gbit/s all-optical modulation with optical control power less than 1
Journal ArticleDOI
160 Gbit/s photonics wireless transmission in the 300-500 GHz band
Xianbin Yu,Shi Jia,Hao Hu,Michael Galili,Toshio Morioka,Peter Uhd Jepsen,Leif Katsuo Oxenløwe +6 more
TL;DR: In this article, a single terahertz (THz) emitter and modulating 25 GHz spaced 8 channels (20 Gbps per channel) in the 300-500 GHz band was demonstrated.
Journal ArticleDOI
Orbital Angular Momentum States Enabling Fiber-based High-dimensional Quantum Communication
Daniele Cozzolino,Davide Bacco,Beatrice Da Lio,Kasper Ingerslev,Yunhong Ding,Kjeld Dalgaard,Poul Kristensen,Michael Galili,Karsten Rottwitt,Siddharth Ramachandran,Leif Katsuo Oxenløwe +10 more
TL;DR: In this paper, the authors use an air-core fiber supporting orbital angular momentum (OAM) modes to faithfully transmit qudits, and four OAM quantum states and their superpositions are created, propagated over a 1.2km fiber, and detected.
Journal ArticleDOI
Efficient electro-optic modulation in low-loss graphene-plasmonic slot waveguides
Yunhong Ding,Xiaowei Guan,Xiaolong Zhu,Hao Hu,Sergey I. Bozhevolnyi,Leif Katsuo Oxenløwe,Kaiyun Jin,Niels Asger Mortensen,Niels Asger Mortensen,Sanshui Xiao +9 more
TL;DR: The results highlight the potential of graphene plasmonic leaky-mode hybrid waveguides to realize active ultra-compact devices for optoelectronic applications and achieve a tunability of 0.13 dB μm-1 for fabricated graphene-plasMonic waveguide devices with extremely low insertion loss.
