Dongheon Ha, Zhiqiang Fang, Nikolai B. Zhitenev
The demand for lightweight, cost-effective, and/or flexible electronic and optoelectronic devices drives research toward new materials advancing the desired functionality or reducing manufacturing costs. Paper, being in addition an earth abundant and

Rydberg Atom Electric-Field Metrology

November 28, 2017
Author(s)
Joshua A. Gordon, Christopher L. Holloway, Matthew T. Simons
We present a technique which shows great promise for realizing an atomic standard measurement of RF fields that is intrinsically calibrated, directly linked to the SI and atomic structural constants. This technique relies on the reponse of Rydberg atoms to

Adam J. Biacchi, Brian G. Alberding, Son T. Le, Joseph A. Hagmann, Sugata Chowdhury, Curt A. Richter, Edwin J. Heilweil, Angela R. Hight Walker
The vast majority of nanoscale 2D materials are synthesized by exfoliation or gas phase deposition techniques. Alternatively, bottom-up colloidal solution syntheses offer a scalable and cost-efficient means of producing 2D nanomaterials in high yield

Superconducting Optoelectronic Circuits for Neuromorphic Computing

March 23, 2017
Author(s)
Jeffrey M. Shainline, Sonia M. Buckley, Richard P. Mirin, Sae Woo Nam
We propose a hybrid semiconductor-superconductor hardware platform for the implementation of neural networks and large-scale neuromorphic computing. The platform combines semiconducting few-photon light-emitting diodes with superconducting-nanowire single

Yichen Shuai, Deyin Zhao, Corey A. Stambaugh, John R. Lawall, Weidong Zhou, Yonghao Liu
We demonstrate here a surface-normal ultracompact Fano resonance electrooptic spatial light modulator employing a stacked photonic crystal membrane capacitor-like structure. Vertically coupled optical resonance near 1.5 μm was observed, and both blue and

High-efficiency superconducting nanowire single-photon detectors fabricated from MoSi thin-films

Varun B. Verma, Boris Korzh, Felix Bussieres, Robert D. Horansky, Shellee D. Dyer, Adriana E. Lita, Igor Vayshenker, Francesco Marsili, Matthew D. Shaw, Hugo Zbinden, Richard P. Mirin, Sae Woo Nam
We report on MoSi SNSPDs which achieved high system detection efficiency (87.1 ± 0.5% at 1542 nm) at 0.7 K and we demonstrate that these detectors can also be operated with saturated internal efficiency at a temperature of 2.3 K in a Gifford-McMahon

High-performing visible-blind photodetectors based on SnO2/CuO nanoheterojunctions

December 14, 2015

Ratan K. Debnath, Ting Xie, MD R. Hasan, Nhan V. Nguyen, Abhishek Motayed
We report on the significant performance enhancement of SnO2 thin film ultraviolet (UV) photodetectors (PDs) through incorporation of CuO/SnO2 pn nanoscale heterojuctions. The nanoheterojunctions are self-assembled by sputtering Cu clusters that oxidize in

Diffraction limited focusing and directing of gap plasmons by a metal-dielectric-metal lens

Author(s)
Brian S. Dennis, David Czaplewski, Michael Haftel, Daniel Lopez, Girsh Blumberg, Vladimir Aksyuk
Passive optical elements can play key roles in photonic applications such as plasmonic integrated circuits. Here we experimentally demonstrate passive gap-plasmon focusing and directing in two-dimensions. This is accomplished using a high numerical

Brian S. Dennis, Michael Haftel, David Czaplewski, Daniel Lopez, Girsh Blumberg, Vladimir Aksyuk
The miniaturization of photonic devices is fundamentally limited by the index of refraction of the constituent materials if light is confined in dielectric nanostructures. By coupling electromagnetic fields to metal's free electrons plasmonic devices

August 24, 2014
Author(s)
Jeffrey A. Jargon, DongJoon Lee, JaeYong Kwon
We present a photonic-assisted time-domain measurement technique for exploring millimeter-wave propagation through a W-band waveguide. The electric fields, guided inside a rectangular waveguide, are sampled using a sub-millimeter-scale electro-optic probe
