25Gb/s 1V-driving CMOS ring modulator with integrated thermal tuning
Guoliang Li,Xuezhe Zheng,Jin Yao,Hiren D. Thacker,Ivan Shubin,Ying Luo,Kannan Raj,John E. Cunningham,Ashok V. Krishnamoorthy +8 more
TL;DR: A high-speed ring modulator that fits many of the ideal qualities for optical interconnect in future exascale supercomputers and fits in a compact 400 μm2 footprint is reported.
Journal ArticleDOI
Ultralow-loss, high-density SOI optical waveguide routing for macrochip interconnects
Guoliang Li,Jin Yao,Hiren D. Thacker,Attila Mekis,Xuezhe Zheng,Ivan Shubin,Ying Luo,Jin-Hyoung Lee,Kannan Raj,John E. Cunningham,Ashok V. Krishnamoorthy +10 more
TL;DR: This work reports optical waveguides up to one meter long with 0.026 dB/cm loss fabricated in a 300nm thick SOI CMOS process and demonstrates a complete toolbox for ultralow-loss, high-density waveguide routing for macrochip interconnects.
Proceedings ArticleDOI
A 3D-IC Technology with Integrated Microchannel Cooling
D.C. Sekar,Calvin King,B. Dang,Todd J. Spencer,Hiren D. Thacker,Paul F. Joseph,Muhannad S. Bakir,James D. Meindl +7 more
TL;DR: A 3D-IC with integrated microchannel cooling is demonstrated in this article, where the demonstrated silicon die contain a through-silicon copper via density of 2500/cm2 integrated within the microchannel heat sink.
Journal ArticleDOI
Ring Resonator Modulators in Silicon for Interchip Photonic Links
Guoliang Li,Ashok V. Krishnamoorthy,Ivan Shubin,Jin Yao,Ying Luo,Hiren D. Thacker,Xuezhe Zheng,Kannan Raj,John E. Cunningham +8 more
TL;DR: In this article, the authors present an in-depth discussion of practical microring modulators in silicon, covering their performance metrics, design tradeoffs, optimization, p-n junction geometries, complex ring configurations, and tuning solutions.
Journal ArticleDOI
Exploiting CMOS Manufacturing to Reduce Tuning Requirements for Resonant Optical Devices
Ashok V. Krishnamoorthy,Xuezhe Zheng,Guoliang Li,Jin Yao,Thierry Pinguet,Attila Mekis,Hiren D. Thacker,Ivan Shubin,Ying Luo,Kannan Raj,John E. Cunningham +10 more
TL;DR: In this paper, the authors quantify intrawafer and interwafer variation of the position and relative spacing of resonance wavelengths for the microring arrays and confirm prior predictions that the absolute resonance positions of such devices cannot be controlled across wafers or even across reticles within a wafer.
