Journal ArticleDOI
Room-temperature InP distributed feedback laser array directly grown on silicon
Zhechao Wang,Bin Tian,Marianna Pantouvaki,W Guo,Philippe Absil,Joris Van Campenhout,Clement Merckling,Dries Van Thourhout +7 more
TL;DR: In this article, an optically pumped InP-based distributed feedback laser array was demonstrated for wavelength division multiplexing applications on (001)-silicon operating at room temperature.
Journal ArticleDOI
Ultrasmall Si-nanowire-based polarization rotator
Zhechao Wang,Daoxin Dai +1 more
TL;DR: In this paper, a polarization rotator based on asymmetrical Si nanowires is presented and optimized for high polarization rotation efficiency (almost 100%) with a very small conversion length (10 μm) and consequently becomes very compact.
Journal ArticleDOI

Zhechao Wang,Amin Abbasi,Utsav D. Dave,Andreas De Groote,Sulakshna Kumari,Bernadette Kunert,Clement Merckling,Marianna Pantouvaki,Yuting Shi,Bin Tian,Kasper Van Gasse,Jochem Verbist,Ruijun Wang,Weiqiang Xie,Jing Zhang,Yunpeng Zhu,Johan Bauwelinck,Xin Yin,Zeger Hens,Joris Van Campenhout,Bart Kuyken,Roel Baets,Geert Morthier,Dries Van Thourhout,Gunther Roelkens +24 more
TL;DR: In this paper, the most recent progress in this field is reviewed, covering the integration approaches of III-V-to-silicon bonding, transfer printing, epitaxial growth and the use of colloidal quantum dots.
Journal ArticleDOI
Highly efficient nonuniform grating coupler for silicon-on-insulator nanophotonic circuits
TL;DR: The measured waveguide-to-fiber coupling efficiency of 64% (-1.9 dB) for the transverse electric polarization is achieved by the present nonuniform grating coupler directly defined on a regular silicon-on-insulator wafer.
Journal ArticleDOI
A III-V-on-Si ultra-dense comb laser.
Zhechao Wang,Kasper Van Gasse,V Valentina Moskalenko,Sylwester Latkowski,Eajm Erwin Bente,Bart Kuyken,Gunther Roelkens +6 more
TL;DR: A demonstration of a III-V-on-Si comb laser that can function as a compact, low-cost frequency comb generator after frequency stabilization and the use of low-loss passive silicon waveguides enables the integration of a long laser cavity, which enables the laser to be locked in the passive mode at a record-low 1 GHz repetition rate.
