Germanium Mid-Infrared Photonic Devices [PDF]
Journal of Lightwave Technology, 2017 Germanium based photonic devices can play a significant role in several applications, particularly in the so-called fingerprint wavelength region. Here, we review our recent results on mid-infrared germanium photonic devices that show promising performance in the 2–7.5 μm wavelength range.

Searching water megamasers by using mid-infrared spectroscopy (I): Possible mid-infrared indicators [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Water megamasers at 22 GHz with a gas disc configuration in galaxies provide the most precise measurements of supermassive black hole masses, as well as independent constraints on the Hubble constant in the nearby universe. The existence of other maser types, such as jet or outflow masers, represents another tracer for AGN ...
