High temperature, magnetic field assisted (sub)THz quantum cascade laser

, 2009
We demonstrate magnetic field assisted, (sub)THz quantum cascade laser operating above 200 K. This is achieved through the application of strong magnetic fields which provide an additional lateral confinement in order to suppress non-radiative ...

Intensity noise and modulation dynamics of an epitaxial mid-infrared interband cascade laser on silicon

APL Photonics
Interband cascade lasers typically have significantly lower threshold current and power consumption than quantum cascade lasers. They can also have advantages regarding costs and compactness with the photonic integration onto silicon substrates by ...

Free-running ring quantum cascade laser with 50 kHz linewidth

JPhys Photonics
We report on the noise characterization of a free-running ring quantum cascade laser resonator emitting a single frequency mode around 7.7 $\mu$ m. Using a gas cell filled with N $ _2$ O as a frequency-to-voltage discriminator, we measured the frequency ...
