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…
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…
Charge Transport in Interband Cascade Lasers: An Ab-Initio Self-Consistent Model
Andreas Windischhofer, Nikola Opačak, Benedikt Schwarz
Interband cascade lasers (ICLs) stand out due to their low threshold current and minimal power consumption, rendering them viable sources for compact and mobile devices in the mid-…
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…
Impact of higher-order dispersion on frequency-modulated combs
Nikola Opačak, Barbara Schneider, Jérôme Faist +1
Frequency-modulated (FM) combs form spontaneously in free-running semiconductor lasers and possess a vast potential for spectroscopic applications. Despite recent progress in obtai…
