Rotationally Resolved Mid-infrared Spectroscopy of (16) Psyche
Asteroid (16) Psyche is theorized to be an exposed iron core of a primordial asteroid and is the target of the upcoming NASA Psyche mission. Recent observations of Psyche identified the presence of rotational heterogeneity, a fine-grained regolith ...

Mid-Infrared Fiber Amplification of a DFB Interband Cascade Laser
The limited availability of powerful, tunable, and reliable mid-infrared sources has historically prevented their widespread adoption in spectroscopy applications, even if most greenhouse gases’ fundamental absorption lines are found in this region of ...

Mid-Infrared Spectroscopy (MIR)
Mid-infrared spectroscopy (MIR) has revolutionised the approach to food integrity analysis as a non-destructive and non-invasive technique. In terms of instrumentation, it can be found in desktop or portable forms and it is quick, highly sensitive and robust technique, providing a comprehensive array of spectral data that encode the molecular structure

Dendritic Plasmonics for Mid-Infrared Spectroscopy
Metallic nanostructures that exhibit tailored optical resonances spanning from the near to mid-infrared spectral range are of particular interest for spectroscopic and optical measurements in these spectral domains that can benefit from localized surface-enhancement effects.

Mid-infrared photonics devices in SOI
In this paper we present silicon photonics devices designed for the 3-4µm wavelength region including waveguides, MMIs, ring resonators and Mach-Zehnder interferometers. The devices are based on silicon on insulator (SOI) platform. We show that 400-500nm

Mid-infrared spectroscopy of candidate active galactic nuclei-dominated submillimeter galaxies [PDF]
Spitzer spectroscopy has revealed that ≃80% of submm galaxies (SMGs) are starburst (SB)-dominated in the mid-infrared. Here we focus on the remaining ≃20% that show signs of harboring powerful active galactic nuclei (AGNs).

Quantum Cascade Laser Frequency Combs
It was recently demonstrated that broadband quantum cascade lasers can operate as frequency combs. As such, they operate under direct electrical pumping at both mid-infrared and THz frequencies, making them very attractive for dual-comb spectroscopy ...

Mid‐Infrared Single‐Photon Compressive Spectroscopy
Abstract Sensitive mid‐infrared (MIR) spectroscopy plays an indispensable role in various photon‐starved conditions. However, the detection sensitivity of conventional MIR spectrometers is severely limited by excessive noises of the involved infrared sensors, especially for multi‐pixel arrays in parallel spectral ...

Infrared fibres in astronomical instrumentation [PDF]
For several years multi-object spectroscopy systems have been available for carrying out survey work in the visible region, but until very recently there has not been a system for the near infrared region.

Mid-Infrared and Infrared Emission Spectroscopy of Cu-Exchanged Montmorillonite [PDF]
Middle Infrared Spectroscopy (Mid-IR) and Infrared Emission Spectroscopy (IES) were employed to characterise Cu-exchanged montmorillonites, which were derived from two different types of montmorillonite clays, Ca-exchanged montmorillonite (Cheto clay ...
