Mid-infrared long-pass filter for high-power applications based on grating diffraction [PDF]
, 2019 A gold-coated silicon grating has been developed, enabling efficient spatial separation of broadband mid-infrared (MIR) beams with wavelengths >5 μm from collinearly propagating, broadband, high-power light in the near-infrared (NIR) spectral range ...

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.

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 ...

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.

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 ...

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.
