Modulation instability and frequency-comb generation in hybrid quadratic-cubic resonators with spectral filtering
Minji Shi, Nicolas Englebert, François Leo +2
We present an analytical and numerical investigation into the phenomenon of filter-induced modulation instability in passive hybrid optical resonators exhibiting quadratic and cubi…
Tunable megawatt-scale sub-20 fs visible pulses from a fiber laser source
Mohammed Sabbah, Robbie Mears, Leah R. Murphy +4
Ultrafast laser pulses that are both tunable in wavelength and very short in duration are essential tools in fields ranging from biomedical imaging to ultrafast spectroscopy. While…
Resonance-free deep ultraviolet to near infrared supercontinuum generation in a hollow-core antiresonant fibre
Mohammed Sabbah, Robbie Mears, Kerrianne Harrington +4
Supercontinuum generation in the ultraviolet spectral region is challenging in solid-core optical fibres due to solarization and photodarkening. Antiresonant hollow-core fibres hav…
Very-Large-Scale Reconfigurable Intelligent Surfaces for Dynamic Control of Terahertz and Millimetre Waves
Yury Malevich, Said Ergoktas, Gokhan Bakan +2
Unlocking the potential of terahertz (THz) and millimetre (mm) waves for next generation communications and imaging applications requires reconfigurable intelligent surfaces (RIS)…
Walk-off induced dissipative breathers and dissipative breather gas in microresonators
A. Villois, D. N. Puzyrev, D. V. Skryabin +1
Dissipative solitons in optical microcavities have attracted significant attention in recent years due to their direct association with the generation of optical frequency combs. H…
Carrier-resolved real-field theory of multi-octave frequency combs
Danila N. Puzyrev, Dmitry V. Skryabin
Optical frequency combs are pillars of precision spectroscopy, and their microresonator realization serves applications where miniaturization and large tooth separation are importa…
