Miniaturized frequency comb sources across hard-to-access spectral regions, ie mid-and far-
infrared, have long been sought. Four-wave-mixing based Quantum Cascade Laser combs …

We present ultra-broadband room temperature monolithic terahertz quantum cascade laser
(QCL) sources based on intra-cavity difference frequency generation, emitting continuously …

Millimeter wave (mmWave) generation using photonic techniques has so far been limited to
the use of near-infrared lasers that are down-converted to the mmWave region. However …

Using a 10.5-GHz resonant electro-optic modulator placed inside a resonant optical cavity,
we generated an optical frequency comb with a span wider than 3?? THz. The optical …

Quantum cascade laser (QCL) frequency combs are a promising candidate for chemical
sensing and biomedical diagnostics,,–. They are electrically pumped and compact, making …

Controlling the coherence between light and matter has enabled the radiation of
electromagnetic waves with a spectral purity and stability that defines the Système …
