Tightly Confined Surface Acoustic Waves as Microwave-to-Optical Transduction Platforms in the Quantum Regime

September 26, 2022
Author(s)
Ryan DeCrescent, Zixuan Wang, Poolad Imany, Robert Boutelle, Corey McDonald, Travis Autry, John Teufel, Sae Woo Nam, Richard Mirin
Surface acoustic waves (SAWs) coupled to quantum dots (QDs), trapped atoms and ions, and point defects have been proposed as quantum transduction platforms, yet the requisite coupling rates and cavity lifetimes have not been experimentally established

3D Imaging from Passive Scattered Light using Plenoptic Information

July 15, 2022
Author(s)
James Leger, Connor Hashemi, Jarvis Haupt, Di Lin, Tianqi Luo, Abhinav Sambasivan, Takahiro Sasaki, Joseph Talgader, Gary Meyer, Michael Tetzlaff, Erich N. Grossman
We use plenoptic measurements of visible, infrared, and THz radiation to locate and image objects that are hidden from direct view by detecting their passive radiation scattered from rough surfaces.

Ultra-low Power Dual Frequency Comb Ranging

June 30, 2022
Author(s)
Emily Caldwell, Laura Sinclair, Jean-Daniel Deschenes, Nathan R. Newbury
Dual comb ranging is a well-established method of laser-based ranging that exploits frequency combs to provide absolute, high-precision measurements. It suffers, however, from a significant power penalty when compared with conventional FMCW LIDAR. Here, we

A continuum of bright and dark pulse states in a photonic-crystal resonator

June 6, 2022
Author(s)
Su-Peng Yu, Erwan Lucas, Jizhao Zang, Scott Papp
Nonlinearity is a powerful determinant of physical systems. Controlling nonlinearity leads to interesting states of matter and new applications. In optics, diverse families of continuous and discrete states arise from balance of nonlinearity and group

Intrinsically accurate sensing with an optomechanical accelerometer

May 18, 2022
Author(s)
Benjamin Reschovsky, David Long, Feng Zhou, Yiliang Bao, Richard A. Allen, Jason J. Gorman, Thomas W. LeBrun
We demonstrate a microfabricated optomechanical accelerometer that is capable of percent-level accuracy without external calibration. To achieve this capability, we use a mechanical model of the device behavior that can be characterized by the thermal

Time Programmable Frequency Comb

May 15, 2022
Author(s)
Emily Caldwell, Laura Sinclair, Nathan R. Newbury, Jean-Daniel Deschenes
We demonstrate a programmable optical frequency comb that emits coherent pulses with user-specified time and phase at sub-10 attosecond accuracy while maintaining the underlying referenced stability characteristic of combs.

A self-validated detector for characterization of quantum network components

May 7, 2022
Author(s)
Anouar Rahmouni, Thomas Gerrits, Alan Migdall, Oliver T. Slattery, Ping-Shine Shaw, Joseph P. Rice
We are developing a nearly polarization-independent, low-cost optical trap detector between 1000 nm and 1550 nm for optical power measurements. A NIST-traceable optical power calibration of this trap detector showed a promising result.

White Rabbit-assisted quantum network node synchronization with quantum channel coexistence

May 7, 2022
Author(s)
Thomas Gerrits, Ivan Burenkov, Ya-Shian Li-Baboud, Anouar Rahmouni, DJ Anand, FNU Hala, Oliver T. Slattery, Abdella Battou, Sergey Polyakov
We show that the Ethernet-based time transfer protocol 'White Rabbit' can synchronize two distant quantum-networked nodes to within 4 ps, enabling HOM interference at >90 % visibility using 17.6 ps FWHM single-photons coexisting with White Rabbit.
