PatentDOI
Compact and low loss Y-junction for submicron silicon waveguide
TL;DR: In this article, a low-loss and wavelength insensitive Y-junction for submicron silicon waveguides was proposed using FDTD and particle swarm optimization (PSO).
Journal ArticleDOI
Ultralow loss single layer submicron silicon waveguide crossing for SOI optical interconnect
Yangjin Ma,Yi Zhang,Shuyu Yang,Ari Novack,Ran Ding,Andy Eu-Jin Lim,Guo-Qiang Lo,Tom Baehr-Jones,Michael Hochberg +8 more
TL;DR: Compact, broadband, ultralow loss silicon waveguide crossings operating at 1550 nm and 1310 nm, fabricated in a CMOS-compatible process using 248 nm optical lithography with a single etch step.
Journal ArticleDOI
Ultralow drive voltage silicon traveling-wave modulator
Tom Baehr-Jones,Ran Ding,Yang Liu,Ali Ayazi,Thierry Pinguet,Nicholas C. Harris,Matthew Streshinsky,Poshen Lee,Yi Zhang,Andy Eu-Jin Lim,Tsung-Yang Liow,Selin H. G. Teo,Guo-Qiang Lo,Michael Hochberg +13 more
TL;DR: A CMOS-compatible broadband traveling-wave modulator based on a reverse-biased pn junction is demonstrated, demonstrating operation with a drive voltage of 0.63 Vpp at 20 Gb/s, a significant improvement in the state of the art.
Journal ArticleDOI
Silicon Photonics: The Next Fabless Semiconductor Industry
TL;DR: The same foundries and processes that were developed to build transistors are being repurposed to build chips that can generate, detect, modulate, and otherwise manipulate light as discussed by the authors.
Journal ArticleDOI
A high-responsivity photodetector absent metal-germanium direct contact
Yi Zhang,Shuyu Yang,Yisu Yang,Michael N. Gould,Noam Ophir,Andy Eu-Jin Lim,Guo-Qiang Lo,Peter Magill,Keren Bergman,Tom Baehr-Jones,Michael Hochberg +10 more
TL;DR: A Ge-on-Si photodetector without doped Ge or Ge-metal contacts is reported, despite the simplified fabrication process, and it is demonstrated that dark current is less than 1µA under both bias conditions.
