Journal ArticleDOI
Effective Electro-Optical Modulation with High Extinction Ratio by a Graphene–Silicon Microring Resonator
Yunhong Ding,Xiaolong Zhu,Sanshui Xiao,Hao Hu,Lars Hagedorn Frandsen,N. Asger Mortensen,Kresten Yvind +6 more
TL;DR: This work comprehensively study the interaction between graphene and a microring resonator, and its influence on the optical modulation depth, and demonstrates graphene-siliconmicroring devices showing a high modulation depth.
Journal ArticleDOI
Single-source chip-based frequency comb enabling extreme parallel data transmission
Hao Hu,Francesco Da Ros,Minhao Pu,Feihong Ye,Kasper Ingerslev,Edson Porto da Silva,Nooruzzaman,Yoshimichi Amma,Yusuke Sasaki,Takayuki Mizuno,Yutaka Miyamoto,Luisa Ottaviano,Elizaveta Semenova,Pengyu Guan,Darko Zibar,Michael Galili,Kresten Yvind,Toshio Morioka,Leif Katsuo Oxenløwe +18 more
TL;DR: A frequency comb realized by a non-resonant aluminium-gallium-arsenide-on-insulator (AlGaAsOI) nanowaveguide with 66% pump-to-comb conversion efficiency is presented, which is significantly higher than state-of-the-art resonant comb sources.
Journal ArticleDOI
Demonstration of 5.1 Tbit/s data capacity on a single-wavelength channel.
Hans Christian Hansen Mulvad,Michael Galili,Leif Katsuo Oxenløwe,Hao Hu,Anders Clausen,Jesper Bevensee Jensen,Christophe Peucheret,Palle Jeppesen +7 more
TL;DR: For the first time, error-free performance with a bit error rate less than 10(-9) is demonstrated for the 5.1 Tbit/s data signal.
Journal ArticleDOI
Nonlinear properties of and nonlinear processing in hydrogenated amorphous silicon waveguides.
Bart Kuyken,Hua Ji,Stéphane Clemmen,Shankar Kumar Selvaraja,Hao Hu,Minhao Pu,Michael Galili,Palle Jeppesen,Geert Morthier,Serge Massar,Leif Katsuo Oxenløwe,Gunther Roelkens,Roel Baets +12 more
TL;DR: It is observed that the nonlinear optical properties of these waveguides degrade with time, but that this degradation can be reversed by annealing the samples.
Journal ArticleDOI
Nonreciprocal transmission in a nonlinear photonic-crystal Fano structure with broken symmetry
TL;DR: In this article, a simple and ultracompact photonic-crystal structure, where a waveguide is coupled to a single nanocavity, is proposed and experimentally demonstrated, showing very efficient optical diode functionality.
