Yating Wan,Justin Norman,Qiang Li,Michael Kennedy,Di Liang,Chong Zhang,Duanni Huang,Zeyu Zhang,Alan Y. Liu,Alfredo Torres,Daehwan Jung,Arthur C. Gossard,Evelyn L. Hu,Kei May Lau,John E. Bowers +14 more
TL;DR: In this paper, the authors demonstrate record small electrically pumped micro-lasers epitaxially grown on industry standard (001) silicon substrates, achieving a submilliamp threshold of 0.6
Journal ArticleDOI
Heterogeneous silicon photonics sensing for autonomous cars.
Weiqiang Xie,Tin Komljenovic,Jinxi Huang,Minh A. Tran,Michael L. Davenport,Alfredo Torres,Paolo Pintus,John E. Bowers +7 more
TL;DR: The recent research and the development of interferometric optical gyroscopes and LiDAR sensors are presented and a fully integrated gyroscope front-end occupying an area of only 4.5 mm2 is shown.
Journal ArticleDOI
Interband cascade laser on silicon
Alexander Spott,Eric J. Stanton,Alfredo Torres,Michael L. Davenport,Chad L. Canedy,I. Vurgaftman,Mijin Kim,Chul-Soo Kim,Charles D. Merritt,William W. Bewley,Jerry R. Meyer,John E. Bowers +11 more
TL;DR: In this article, the authors demonstrate the integration of interband cascade laser (ICL) on a silicon substrate, which can emit 3.6μm light into silicon-on-insulator waveguides in pulsed mode at temperatures up to 50°C.
Journal ArticleDOI
High-Performance O-Band Quantum-Dot Semiconductor Optical Amplifiers Directly Grown on a CMOS Compatible Silicon Substrate
Songtao Liu,Justin Norman,Mario Dumont,Daehwan Jung,Alfredo Torres,Arthur C. Gossard,John E. Bowers,S. Liu,A. Torres,Arthur C. Gossard,John E. Bowers,D. Jung,J. Norman,M. Dumont +13 more
TL;DR: In this article, high gain and high saturation output power silicon-based semiconductor optical amplifiers (SOAs) are essential elements in future large-scale silicon photonic integrated circuits (PICs) to compensate for compensa...
