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…
Nozaki-Bekki optical solitons
Nikola Opačak, Dmitry Kazakov, Lorenzo L. Columbo +8
Recent years witnessed rapid progress of chip-scale integrated optical frequency comb sources. Among them, two classes are particularly significant -- semiconductor Fabry-Perót las…
Semiconductor ring laser frequency combs with active directional couplers
Dmitry Kazakov, Theodore P. Letsou, Maximilian Beiser +5
Rapid development of Fabry-Perot quantum cascade laser frequency combs has converted them from laboratory devices to key components of next-generation fast molecular spectrometers.…
Spectrally resolved linewidth enhancement factor of a semiconductor frequency comb
Nikola Opačak, Florian Pilat, Dmitry Kazakov +5
The linewidth enhancement factor (LEF) has recently moved into the spotlight of research on frequency comb generation in semiconductor lasers. Here we present a novel modulation ex…
