Towards nano-scale photonics with micro-scale photons: the opportunities and challenges of mid-infrared plasmonics

open access: yesNanophotonics, 2013
Surface plasmon polaritons and their localized counterparts, surface plasmons, are widely used at visible and near-infrared (near-IR) frequencies to confine, enhance, and manipulate light on the subwavelength scale. At these frequencies, surface plasmons

Mid-IR Fiber Sources

open access: yesLasers, Sources, and Related Photonic Devices, 2012
IR Chalcogenide glass fibers have broad transmission in the IR and high intrinsic nonlinearities. These nonlinear processes can be exploited to generate mid-IR sources. We report on mid-IR sources based on these fibers.

Resolved Mid-IR Emission in the Narrow Line Region of NGC 4151 [PDF]

open access: yes, 2002
We present subarcsecond resolution mid infrared images of NGC 4151 at 10.8 micron and 18.2 micron. These images were taken with the University of Florida mid-IR camera/spectrometer OSCIR at the Gemini North 8-m telescope. We resolve emission at both 10.8

Silicon photonic devices for mid-infrared applications

open access: yesNanophotonics, 2014
The mid-infrared (IR) wavelength region (2–20 µm) is of great interest for a number of applications, including trace gas sensing, thermal imaging, and free-space communications.

Mid-IR Fiber Lasers

open access: yesAdvanced Photonics 2016 (IPR, NOMA, Sensors, Networks, SPPCom, SOF), 2016
The last decade has witnessed a marked improvement in the extracted power, optical efficiency and range of available wavelengths emitted from fiber lasers designed for emission in the mid-infrared. In this tutorial, I will briefly review the major advances leading to these improvements and I will outline the challenges ahead.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Mid-IR Photonics

open access: yesOptical Fiber Communication Conference, 2014
Mid-infrared photonic integrated circuits can potentially reduce the cost, power consumption, and footprint of sensors for environmental monitoring, medical diagnostics, and threat detection. This tutorial explores platforms for the manipulation of mid-wave/short-wave infrared signals, with a focus upon silicon photonics.

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...
