Journal ArticleDOI
Cascaded modulator architecture for WDM applications
Kapil Debnath,Liam O'Faolain,Frederic Y. Gardes,Andreas G. Steffan,Graham T. Reed,Thomas F. Krauss +5 more
TL;DR: This work proposes and demonstrates a novel architecture consisting of an array of photonic crystal modulators connected by a dielectric bus waveguide that features very high scalability and the modulators operate with an AC energy consumption of less than 1fJ/bit.
Journal ArticleDOI
Highly efficient optical filter based on vertically coupled photonic crystal cavity and bus waveguide.
TL;DR: In this article, a new optical filter design based on a vertically coupled photonic crystal (PhC) cavity and a bus waveguide monolithically integrated on the silicon-on-insulator platform is presented.
Journal ArticleDOI
Suspended low-loss germanium waveguides for the longwave infrared.
Ahmed Osman,Milos Nedeljkovic,J. Soler Penades,Yangbo Wu,Zhibo Qu,Ali Z. Khokhar,Kapil Debnath,Goran Z. Mashanovich +7 more
TL;DR: The authors' MIR waveguides create a new path toward long wavelength sensing in the fingerprint region by defining holes alongside the core providing access to the buried oxide layer and the underlying Si layer so that they can be wet etched using hydrofluoric acid and tetramethylammonium hydroxide.
Proceedings ArticleDOI
Silicon optical modulators for integrated transceivers
Graham T. Reed,David J. Thomson,Frederic Y. Gardes,Goran Z. Mashanovich,Youfang Hu,Ke Li,P.W. Wilson,Lars Zimmermann,Henri Porte,Bernhard Goll,Horst Zimmermann,D. Knoll,Stefan Lischke,S.W. Chen,Shawn S. H. Hsu,J-M. Fedeli,Kapil Debnath,Thomas F. Krauss,Liam O'Faolain +18 more
TL;DR: In this article, the authors present modulators developed in the projects "HELIOS" and "UK Silicon Photonics" integration with modulator driver to produce the first silicon modulator fully integrated with BiCMOS, and multiplexed photonic crystal modulators for ultra-low power operation.
Journal ArticleDOI
Silicon Nitride Photonics for the Near-Infrared
Thalia Dominguez Bucio,Cosimo Lacava,Marco Clementi,Joaquin Faneca,Ilias Skandalos,Anna Baldycheva,Matteo Galli,Kapil Debnath,Periklis Petropoulos,Frederic Y. Gardes +9 more
TL;DR: In this paper, the authors focus on the progress in the demonstration of enhanced functionalities in the near infrared wavelength regime with their low temperature ( ${^\circ}$ C) SiN platform.
