The discovery that externally-driven nonlinear optical resonators can sustain ultrashort pulses cor- responding to coherent optical frequency combs has enabled landmark advances in applications from telecommunications to sensing. The research focus has

A Photoacoustic Technique for Measuring Soot Deposition on Surfaces

March 13, 2024
Author(s)
Ryan Falkenstein-Smith, Amy Mensch
This study investigates a soot deposition measurement technique that relies on the photoacoustic effect of soot. A non-invasive and reliable soot deposition measurement tool would be helpful for fire investigators to quantify burn patterns in a fire scene

Low-power, agile electro-optic frequency comb spectrometer for integrated sensors

March 11, 2024
Author(s)
Kyunghun Han, David Long, Sean Bresler, Junyeob Song, Yiliang Bao, Benjamin Reschovsky, Kartik Srinivasan, Jason J. Gorman, Vladimir Aksyuk, Thomas W. LeBrun
Sensing platforms based upon photonic integrated circuits have shown considerable promise; however, they require corresponding advancements in integrated optical readout technologies. Here, we present an on-chip spectrometer that leverages an integrated

DC to GHz measurements of a near-ideal 2D material: P+ monolayers

March 8, 2024
Author(s)
Neil M. Zimmerman, Antonio Levy, Pradeep Namboodiri, Joshua M. Pomeroy, Xiqiao Wang, Joseph Fox, Richard M. Silver
P+ monolayers in Si are of great scientific and technological interest, both intrinsically as a material in the "ideal vacuum" of crystalline Si, and because they are showing great promise as qubits of electron and nuclear spin. The GHz complex

An Open Source Iris Segmentation Algorithm for Non-ideal Images

March 7, 2024
Author(s)
George W. Quinn
This document describes a new approach to localizing the iris boundaries in non-ideal iris images. The proposed algorithm starts by applying a series of morphological operations to enhance the salience of the iris boundaries while mitigating the impact of

Comparison of N-glycopeptide to released N-glycan abundances and the influence of glycopeptide mass and charge state on N-linked glycosylation of IgG antibodies
