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 ...

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.
