Accurate Integral Counting Using Multi-channel Analyzers

May 1, 2020
Author(s)
Ryan P. Fitzgerald, Lynne E. King
Many techniques in radionuclide metrology rely on accurate measurement of the total count rate, that is integral counting, from a detector. In modern experiments, this can be achieved by integrating the total number of counts in an energy spectrum produced

AlGaN/GaN core-shell heterostructures for nanowire UV LEDs

May 1, 2020
Author(s)
Matthew D. Brubaker, Bryan T. Spann, Kristen L. Genter, Alexana Roshko, Paul T. Blanchard, Todd E. Harvey, Kristine A. Bertness
Nanowire-based ultraviolet (UV) LEDs hold great promise as nanoscale light sources, potentially enabling advanced scanning microscopy probes capable of optoelectronic sensing and near-field scanning photolithography. In this work, we report on the

All-fiber frequency comb at 2 mm providing 1.4-cycle pulses

May 1, 2020

Sida Xing, Abijith S. Kowligy, Daniel Lesko, Alexander Lind, Scott Diddams
We report an all-fiber approach to generating sub-2-cycle pulses at 2 µm and a corresponding octave-spanning optical frequency comb. Our configuration leverages mature erbium:fiber laser technology at 1.5 µm to provide a seed pulse for a thulium-doped

Leveraging standard geospatial representations for industrial augmented reality

May 1, 2020
Author(s)
Teodor I. Vernica, Aaron M. Hanke, William Z. Bernstein
Due to its tremendous potential, Augmented Reality (AR) has experienced a recent surge in adoption and integration within the manufacturing enterprise. While industrial AR has been successfully implemented and shown to have significant benefits in a

Low-loss, high-bandwidth fiber-to-chip coupling using capped adiabatic tapered fibers

May 1, 2020
Author(s)
Saeed Khan, Jeff Shainline, Richard Mirin, Sae Woo Nam, Sonia Buckley, Jeff Chiles
We demonstrate adiabatically tapered fibers terminating in sub-micron tips that are clad with a higher-index material for coupling to an on-chip waveguide. This cladding enables coupling to a high-index waveguide without losing light to the buried oxide. A
