Journal ArticleDOI
Large-Area Metasurface Perfect Absorbers from Visible to Near-Infrared.
Gleb M. Akselrod,Jiani Huang,Thang B. Hoang,Patrick T. Bowen,Logan Su,David R. Smith,Maiken H. Mikkelsen +6 more
TL;DR: An absorptive metasurface based on film-coupled colloidal silver nanocubes is demonstrated and the resonance can be tuned from the visible to the near-infrared.
Journal ArticleDOI
Fabrication-constrained nanophotonic inverse design.
TL;DR: A general inverse design algorithm for nanophotonic devices that directly incorporates fabrication constraints is described and a compact, broadband 1 × 3 power splitter is designed on a silicon photonics platform.
Journal ArticleDOI
Inverse design and demonstration of a compact on-chip narrowband three-channel wavelength demultiplexer
TL;DR: In this paper, an inverse design and experimentally demonstrate a three-channel wavelength demultiplexer with 40 nm spacing (1500, 1540, and 1580 nm) with a footprint of 24.75 μm2.
Journal ArticleDOI
On-chip integrated laser-driven particle accelerator.
Neil V. Sapra,Ki Youl Yang,Dries Vercruysse,Kenneth J. Leedle,Dylan S. Black,R. Joel England,Logan Su,Rahul Trivedi,Yu Miao,Olav Solgaard,Robert L. Byer,Jelena Vuckovic +11 more
TL;DR: An experimental demonstration of a waveguide-integrated DLA that was designed using a photonic inverse-design approach and infer a maximum energy gain of 0.915 kilo–electron volts over 30 micrometers, corresponding to an acceleration gradient of 30.5 mega-electron volt-scale DLA.
Journal ArticleDOI
Fully-automated optimization of grating couplers.
TL;DR: This work designs a fiber-to-chip blazed grating with under 0.2 dB insertion loss that requires a single etch to fabricate and no back-reflector and can reliably design efficient couplers to have multiple functionalities in different geometries.
