Star Formation in the Bok Globule CB54 [PDF]
, 2007 We present mid-infrared (10.4, 11.7, and 18.3 μm) imaging intended to locate and characterize the suspected protostellar components within the Bok globule CB54. We detect and confirm the protostellar status for the near-infrared source CB54YC1-II.

Luminescent ion-doped transparent glass ceramics for mid-infrared light sources [invited]
Optics Express, 2020 Glass ceramics (GCs), which consist essentially of a homogeneous solid state dispersion of nanocrystals (NCs) embedded in a chemically inert and mechanically robust glass matrix, appear to be an extremely promising class of solid state materials that can be easily tailored into arbitrary shapes, including a new generation of optical fibers, for ...

Sub-picosecond tunable mid-infrared light source for driving high-efficiency optical rectification
Optics Express, 2023 Optical rectification (OR) is a popular way to generate coherent terahertz radiation. Here, we develop a sub-picosecond mid-infrared (mid-IR) light source with a tailored wavelength and pulse duration for enhancing the OR efficiency. Numerical simulations for a LiNbO3-based OR with tilted pulse-front excitation are first conducted to determine the ...

Frequency Chirped Intensity Modulated Mid-Infrared Light Source Based on Optical Parametric Oscillation [PDF]
IEEE Photonics Journal, 2020 Optical carried microwave radar (OCMR) has better resistance to turbulence and scattering than conventional laser radar for using intensity modulated laser beam as detection medium. Intensity modulated mid-infrared source is the key to mid-infrared OCMR system. A frequency chirped intensity modulated mid-infrared light source with tunable wavelength is

Morphological Classification of Local Luminous Infrared Galaxies [PDF]
, 2016 We present an analysis of the morphological classification of 89 luminous infrared galaxies (LIRGs) from the Great Observatories All-sky LIRG Survey (GOALS) sample using non-parametric coefficients and compare their morphology as a function of wavelength.

Semiconductor light sources for near- and mid-infrared spectral ranges
Journal of Physics: Conference Series, 2017 1550 nm band wafer-fused vertical-cavity surface-emitting lasers (VCSELs) and 5-10 μm band multi-stages quantum-cascade lasers (QCL) grown by molecular beam epitaxy (MBE) were fabricated and studied. VCSELs show high output optical power up to 6 mW in single-mode regime (SMSR > 40 dB) and open-eye diagrams at 30 Gbps of standard NRZ at 20°C.
