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 Opačak +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…
Multidimensional optical singularities and their applications
Soon Wei Daniel Lim, Christina M. Spaegele, Federico Capasso
Optical singularities, which are positions within an electromagnetic field where certain field parameters become undefined, hold significant potential for applications in areas suc…
Driven bright solitons on a mid-infrared laser chip
Dmitry Kazakov, Theodore P. Letsou, Marco Piccardo +13
Despite the ongoing progress in integrated optical frequency comb technology, compact sources of short bright pulses in the mid-infrared wavelength range from 3 μm to 12 μm so far…
Metasurface-controlled holographic microcavities
Sydney Mason, Maryna Leonidivna Meretska, Christina Spägele +2
Optical microcavities confine light to wavelength-scale volumes and are a key component for manipulating and enhancing the interaction of light, vacuum states, and matter. Current…
