Mid-infrared supercontinuum generation in soft-glass specialty optical fibers: A review
Progress in Quantum Electronics, 2021Mid-infrared region (2–20 μm) is an important region of electromagnetic spectrum. Most of the molecules including CH4, CO, NO, NO2, C6H6, TNT, NH3, SF6, HNO3, greenhouse gas radiation etc. have their fundamental vibrations in this domain.

Mid-infrared microfiber Bragg gratings
Optics Letters, 2020We report mid-infrared (mid-IR) Bragg gratings fabricated on sub-wavelength-diameter chalcogenide glass (ChG) microfibers. ChG microfibers with diameters around 3 µm are tapered drawn from A s 2 S 3 glass fibers, and the ...

Group IV and III–V semiconductor photonic devices are prime candidates for photonic and opto-electronic (OEIC) applications in the 1.8 to 5.0 µm infrared wavelength range. Si-based active photonics in the GeSn/SiGeSn heterosystem (LDs, PDs, LEDs, amplifiers, EOMs) offers the Si CMOS “foundry advantage” for high-volume low-cost OEIC manufacture. Two MIR

This chapter presents the scope and potentiality of Mid-infrared spectroscopy (MIRS) for food analysis. MIRS has a great potential to detect various components of food, and this technique holds great significance as it provides specific fingerprints for different food products. Mid-infrared range has an appropriate band in the spectrum for quantitative

Mid-infrared optical coherence tomography
Review of Scientific Instruments, 2007A time domain optical coherence tomography (OCT) system is described that uses mid-infrared light (6–8μm). To the best of our knowledge, this is the first OCT system that operates in the mid-infrared spectral region. It has been designed to characterize bioengineered tissues in terms of their structure and biochemical composition.

Abstract In this study the rise times of different fast mid-infrared detectors, i.e. of Ge photon-drag, pyroelectric and HgCdTe detectors are determined with the aid of 30 ps optical-free-induction-decay (OFID) 10 μm Co 2 -laser pulses. The measured rise times are all about 260 ps. This time is limited by the applied oscilloscope.

Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics. Postconference Edition. CLEO '99. Conference on Lasers and Electro-Optics (IEEE Cat. No.99CH37013), 2003
Summary form only given. Application of a far-infrared pulse in the terahertz (THz) frequency range provides an advantage in imaging of chemical and biological materials due to strong molecular resonance in the frequency range. Two dimensional frame imaging of THz illumination is also possible as demonstrated recently.

GaInAsSb Mid-infrared diode lasers
1994 Conference on Lasers and Electro-Optics Europe, 1994For the past six years, Lincoln Laboratory has been developing mid-infrared diode lasers based upon GaInAsSb/AlGaAsSb heterostructures grown on GaSb substrates by molecular beam epitaxy.1-4 Compactness and efficiency make diode lasers very desirable in the mid infrared for optical pumping solid-state lasers and for direct sources in this spectral range,
