For harnessing the full potential of quantum phenomena, light-matter interfaces and
complexly connected quantum networks are required, relying on the joint quantum operation …

Integrated photonics provides an important platform for simulating physical models with high-
performance chip-scale devices, where the lattice size and the time-dependence of a model …

Quantum cascade lasers (QCLs) are a prominent semiconductor laser source operating in
the mid-infrared and terahertz regimes. As is typical with semiconductor lasers, QCLs …

Abstract Interband Cascade Lasers (ICL) have matured into a versatile technological
platform in the mid‐infrared spectral domain. To broaden their applicability even further …

Broadband dual-comb sources allow retrieving Fourier spectra without the need of moving
interferometric components, thereby offering new possibilities for real-time and high …

Here, we propose the construction of acoustic Weyl semimetals in synthetic dimensions
based on a 2D coupling waveguide array under external dynamic modulations. The type-I …

We demonstrate a quantum walk comb in synthetic frequency space formed by externally
modulating a semiconductor optical amplifier operating in the telecommunication …

Optical frequency comb (OFC) emission in quantum cascade lasers (QCLs) is highly
attractive for applications in metrology and sensing. Recently, coherent OFC mode-locking …

Optical combs are laser devices that emit hundreds of color tones simultaneously with
evenly spaced frequencies. Their introduction in the late 1990s revolutionized the use of …

In this work, we demonstrate that in a regime of strong modulation, by generating pulses of
the length of the order of a few cavity lifetimes (hundreds of ps), a broadband quantum …
