A swept-source dual-comb spectrometer on a chip
Johannes Fuchsberger, Theodore P. Letsou, Paul Chevalier +4
Dual-comb spectroscopy (DCS) enables high-speed, high-resolution spectroscopy by down-converting optical spectra to the radio-frequency (RF) domain through the interference of two…
High-power quantum walk frequency combs
Theodore P. Letsou, Johannes Fuchsberger, Nikola OpaÄak +3
High-power, broadband frequency combs generated by semiconductor lasers have profound implications for on-chip spectroscopy. Here, we present a dry-etched racetrack quantum cascade…
Temporal solitons in active optical resonators
Dmitry Kazakov, Federico Capasso, Marco Piccardo
Solitons, as coherent structures that maintain their shape while traveling at constant velocity, are ubiquitous across various branches of physics, from fluid dynamics to quantum f…
Lasing on hybridized soliton frequency combs
Theodore P. Letsou, Dmitry Kazakov, Pawan Ratra +10
Coupling is an essential mechanism that drives complexity in natural systems, transforming single, non-interacting elements into intricate networks with rich physical properties. H…
