The unique structure and properties of the quantum cascade laser have enabled scientists to gain access to a valuable region of the electromagnetic spectrum — the mid-infrared. Through taste and ...

That’s the electromagnetic spectral line of hydrogen, and it’s the always on the air. But studying the H-line is a non-trivial task unless you know how to cascade low-noise amplifiers and ...

"It demonstrates that cascade-engineered devices enhance the capabilities of single crystals in X-ray detection." Just like visible light and radio waves, X-rays are a form of electromagnetic ...
