Journal ArticleDOI
Coherent solid-state LIDAR with silicon photonic optical phased arrays
Christopher V. Poulton,Ami Yaacobi,David B. Cole,Matthew J. Byrd,Manan Raval,Diedrik Vermeulen,Michael R. Watts +6 more
TL;DR: This first demonstration of coherent solid-state light detection and ranging (LIDAR) using optical phased arrays in a silicon photonics platform is presented and paves the way for disruptive low-cost and compact LIDAR on-chip technology.
Journal ArticleDOI
Long-Range LiDAR and Free-Space Data Communication With High-Performance Optical Phased Arrays
Christopher V. Poulton,Matthew J. Byrd,Peter Russo,Erman Timurdogan,Murshed Khandaker,Diedrik Vermeulen,Michael R. Watts +6 more
TL;DR: In this paper, high-performance integrated optical phased arrays along with first-of-their-kind light detection and ranging (LiDAR) and free-space data communication demonstrators are presented.
Journal ArticleDOI
Large-scale silicon nitride nanophotonic phased arrays at infrared and visible wavelengths.
Christopher V. Poulton,Matthew J. Byrd,Manan Raval,Zhan Su,Nanxi Li,Erman Timurdogan,Douglas D. Coolbaugh,Diedrik Vermeulen,Michael R. Watts +8 more
TL;DR: Using the same silicon nitride platform and phased array architecture, it is demonstrated that the first large-aperture visible nanophotonic phased array at 635 nm with an aperture size of 0.064°×0.074° is demonstrated, to the best of the authors' knowledge.
Journal ArticleDOI
Electric field-induced second-order nonlinear optical effects in silicon waveguides
TL;DR: In this paper, direct-current fields across p-i-n junctions in silicon ridge waveguides were applied to perturb the permittivity of the direct-c. Kerr effect and achieve phase-only modulation and second-harmonic generation.
Journal ArticleDOI
A Single-Chip Optical Phased Array in a Wafer-Scale Silicon Photonics/CMOS 3D-Integration Platform
Taehwan Kim,Pavan Bhargava,Christopher V. Poulton,Jelena Notaros,Ami Yaacobi,Erman Timurdogan,Christopher Baiocco,Nicholas M. Fahrenkopf,Seth Kruger,Tat Ngai,Yukta Timalsina,Michael R. Watts,Vladimir Stojanovic +12 more
TL;DR: This article introduces a single-chip OPA realized through wafer-scale 3-D integration of silicon photonics and CMOS, and achieves wide-range 2-D steering over 18.25° beamwidth while consuming 20 mW/element average power.
