We report new mid-infrared observations of the remarkable object IRAS 15099-5856 using the space telescopes AKARI and Spitzer, which demonstrate the presence of prominent crystalline silicate emission...
Phase-Matching and Parametric Conversion for the Mid-Infrared in As2S3 Waveguides
As2S3 Mid-Infrared Phase-Matching Four-Wave Mixing

2013/1/30
We illustrate two As2S3 waveguide designs for four-wave mixing, which can generate 3.03 μm mid-infrared light from a 1.55 μm near-infrared signal source and a 2.05 μm pump source. Through simulations,...
Robust design of Si/Si3N4 high contrast grating mirror for mid-infrared VCSEL application
High contrast grating mirror mid-infrared VCSEL Robust design
font style='font-size:12px;'>
2012/5/28
A Si/Si3N4 high contrast grating mirror has been designed for a VCSEL integration in mid-infrared ({\lambda} = 2.65 $\mu$m). The use of an optimization algorithm which maximizes a VCSEL mirror quality...
