TL;DR: This work demonstrates that the photonic approach can deliver on its promise by digitizing a 41 GHz signal with 7.0 effective bits using a photonic ADC built from discrete components, a 4-5 times improvement over the performance of the best electronic ADCs which exist today.
Journal ArticleDOI
CMOS-Compatible All-Si High-Speed Waveguide Photodiodes With High Responsivity in Near-Infrared Communication Band
Michael W. Geis,Steven J. Spector,Matthew E. Grein,R. T. Schulein,J. U. Yoon,D. M. Lennon,S. Deneault,Fuwan Gan,Franz X. Kaertner,Theodore M. Lyszczarz +9 more
TL;DR: The p-i-n photodiode waveguide as discussed by the authors consists of an intrinsic waveguide 500 times250 nm where the optical mode is confined and two thin, 50nm-thick, doped Si wings that extend 5 mum out from either side of the waveguide.
Journal ArticleDOI
Silicon photonics for compact, energy-efficient interconnects [Invited]
Tymon Barwicz,Hyunil Byun,Fuwan Gan,C.W. Holzwarth,Milos A. Popovic,Peter T. Rakich,Michael R. Watts,Erich P. Ippen,Franz X. Kärtner,Henry I. Smith,Jason S. Orcutt,Rajeev J. Ram,Vladimir Stojanovic,O. O. Olubuyide,Judy L. Hoyt,Steven J. Spector,Michael W. Geis,Matthew E. Grein,Theodore M. Lyszczarz,J. U. Yoon +19 more
TL;DR: A novel reconfigurable, 'hitless' switch that does not perturb the express channels either before, during, or after reconfiguration, and multigigahertz operation of low-power, Mach-Zehnder silicon modulators as well as germanium-on-silicon photodiodes are presented.
Journal ArticleDOI
Silicon waveguide infrared photodiodes with >35 GHz bandwidth and phototransistors with 50 AW -1 response
Michael W. Geis,Steven J. Spector,Matthew E. Grein,J. U. Yoon,D. M. Lennon,Theodore M. Lyszczarz +5 more
TL;DR: SOI CMOS compatible Si waveguide photodetectors are made responsive from 1100 to 1750 nm by Si+ implantation and annealing to make them very competitive when compared to other detector technologies.
Journal ArticleDOI
Submicrosecond submilliwatt silicon-on-insulator thermooptic switch
TL;DR: In this paper, the authors used a thin-silicon-on-insulator material system to make a Mach-Zehnder interferometer thermooptic switches using single-mode strip-Si waveguides.
