Efficient Energy Transfer and Photoluminescence Enhancement in 2D MoS2/bulk InSe van der Waals Heterostructures

April 13, 2025
Author(s)
Michael Altvater, Christopher Stevens, Nicholas Pike, Joshua Hendrickson, Rahul Rao, Sergiy Krylyuk, Albert Davydov, Deep Jariwala, Ruth Patcher, Michael Snure, Nicholas Glavin
Heterostructures between 2D and 3D electron systems remain critically important in developing novel and efficient optoelectronic and electronic devices. In this study, a vertical heterojunction between monolayer MoS2 and bulk InSe was developed. This

Electro-Optic Imaging Millimeter-Wave Propagation On-Wafer

September 27, 2023
Author(s)
Bryan Bosworth, Nick Jungwirth, Jerome Cheron, Franklyn Quinlan, Nate Orloff, Chris Long, Ari Feldman
We demonstrate an electro-optic imaging system for mmWaves propagating along a coplanar waveguide. Using dual optical frequency combs and a polarization resolved microscope, we image signals with bandwidth >100 GHz and >48 dB dynamic range.

Studies of spatial uniformity and jitter in SiC UV SPADs

Joshua Bienfang, Edwin J. Heilweil, Anand Sampath, Gregory Garrett, Jonathan Shuster, Jeremy Smith, Michael Derenge, Daniel Habersat, Reza Gandhi, Sergei Dolinsky, Enrico Bellotti, michael wrabeck
Ultraviolet single-photon avalanche detectors (UV-SPAD) that are low cost, size, weight, and power as well as resilient to shock, high temperatures and stray magnetic fields have a number of applications. SiC is attractive for UV SPADs as it is inherently

Demonstration of Superconducting Optoelectronic Single-Photon Synapses

Saeed Khan, Bryce Primavera, Jeff Chiles, Adam McCaughan, Sonia Buckley, Alexander Tait, Adriana Lita, John Biesecker, Anna Fox, David Olaya, Richard Mirin, Sae Woo Nam, Jeff Shainline
Superconducting optoelectronic hardware is being explored as a path towards artificial spiking neural networks with unprecedented scales of complexity and computational ability. Such hardware combines integrated-photonic components for few-photon, light

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

All-Printed Ultrahigh-Responsivity MoS2 Nanosheet Photodetectors Enabled by Megasonic Exfoliation

July 5, 2022
Author(s)
Lee J. Richter, Lidia Kuo, Vinod Sangwan, Sonal Rangnekar, Ting-Ching Chu, David Lam, Shehao Zhu, Ruipeng Li, Julia Downing, Benjamin Luijten, Lincoln Lauhon, Mark Hersam
Printed two-dimensional materials, derived from solution-processed inks, offer scalable and cost-effective routes to mechanically flexible optoelectronics. With micron-scale control and broad processing latitude, aerosol-jet printing (AJP) is of particular

Fast Near-Infrared Photodetection using III-V Colloidal Quantum Dots

June 29, 2022

Lee J. Richter, Bin Sun, Amin M. Najarian, Chao Zheng, Laxmi K. Sagar, Min-Jae Choi, Xiyan Li, Larissa Levina, Se-Woong Baek, Seungjin Lee, Ahmad R. Kirmani, Jehad Abed, Mengxia Liu, Peicheng Li, Oleksandr Voznyy, Zheng H. Lu, F. Pelayo G. de Arquer, Edward H. Sargent
Colloidal quantum dots (CQDs) are promising materials for IR light detection due to their tunable bandgap and their solution processing; however, to date, the time response of CQD IR photodiodes has been inferior to that provided by Si and InGaAs. We

June 21, 2022
Author(s)
Thomas C. Larason, Steven Grantham, Clarence Zarobila, Yuqin Zong, C Cameron Miller, Michael Schuit, Brian Holland, Stewart Wood, Melissa Krause
As COVID-19 was overtaking the world in the spring of 2020, the National Institute of Standards and Technology began collaborating with the National Biodefense Analysis and Countermeasures Center to study the inactivation of SARS-CoV-2 to different UV and

A pyroelectric detector-based method for low uncertainty spectral irradiance and radiance responsivity calibrations in the infrared using tunable lasers

April 4, 2022
Author(s)
Brian Alberding, John Woodward, Ping-Shine Shaw, Leonard Hanssen, Catherine Cooksey, Joseph P. Rice
The standard uncertainty of detector-based radiance and irradiance responsivity calibrations in the short-wave infrared (SWIR) traditionally has been limited to around 1 % or higher by the low spatial uniformity of detectors used to transfer the scale from

Laser-lithographically written micron-wide superconducting nanowire single-photon detectors

March 23, 2022
Author(s)
Maximilian Protte, Varun Verma, Jan Philipp Hopker, Richard Mirin, Sae Woo Nam, Tim Bartley
In this paper, we demonstrate our results on micron-wide tungsten silicide superconducting nanowire single-photon detectors fabricated by laser lithography. Laser-lithographically written devices allow for fast and easy structuring of large areas while

Heterosubstrate Illumination Effects in III-V Solar Cells

February 16, 2022
Author(s)
Brianna Conrad, Behrang Hamadani
Reference cell-based current versus voltage ( I–V ) measurements assume that the effect of an illumination spectrum on a solar cell's performance can be fully captured by the multiplication of the spectrum with the device's spectral response and subsequent

Control and readout of a superconducting qubit using a photonic link

March 24, 2021
Author(s)
Florent Lecocq, Franklyn Quinlan, Katarina Cicak, Joe Aumentado, Scott Diddams, John Teufel
Delivering on the revolutionary promise of a universal quantum computer will require processors with millions of quantum bits (qubits). In superconducting quantum processors, each qubit is individually addressed with microwave signal lines that connect

Quantum dot lasers - history and future prospects

January 29, 2021
Author(s)
Richard Mirin, John E. Bowers, Justin Norman
We describe the initial efforts to use molecular beam epitaxy to grow InAs quantum dots on GaAs via the Stranski-Krastanow transition. We then discuss the initial efforts to use these quantum dots to demonstrate quantum dot lasers. We discuss the
