Dual backgrounds and their stability during comb generation in microresonators
Boris Sturman, Evgeny Podivilov, Jan Szabados +1
Light states relevant to the comb generation in optical microresonators possess typically dual backgrounds for coupled first-harmonic (FH) and second-harmonic (SH) envelo…
Fine structure of second-harmonic resonances in χ^{(2)} optical microresonators
Jan Szabados, Nicolás Amiune, Boris Sturman +1
Owing to the discrete frequency spectrum of whispering gallery resonators (WGRs), the resonance and phase-matching conditions for the interacting waves in the case of second-harmon…
Frequency comb generation threshold in optical microresonators
Jan Szabados, Boris Sturman, Ingo Breunig
We investigate the threshold of frequency comb generation in lithium niobate whispering gallery microresonators theoretically and experimentally. When generating a freque…
Frequency comb generation via cascaded second-order nonlinearities in microresonators
Jan Szabados, Danila N. Puzyrev, Yannick Minet +5
Optical frequency combs are revolutionising modern time and frequency metrology. In the past years, their range of applications has increased substantially, driven by their miniatu…
Electro-optic eigenfrequency tuning of potassium tantalate-niobate microresonators
Jan Szabados, Christoph S. Werner, Simon J. Herr +2
Eigenfrequency tuning in microresonators is useful for a range of applications including frequency-agile optical filters and tunable optical frequency converters. In most of these…
Pockels-effect-based adiabatic frequency conversion in ultrahigh- microresonators
Yannick Minet, Luís Reis, Jan Szabados +4
Adiabatic frequency conversion has some key advantages over nonlinear frequency conversion. No threshold and no phase-matching conditions need to be fulfilled. Moreover, it exhibit…
Frequency comb up- and down-conversion in a synchronously-driven optical microresonator
Simon J. Herr, Victor Brasch, Jan Szabados +6
Optical frequency combs are key to optical precision measurements. While most frequency combs operate in the near-infrared regime, many applications require combs at mid-infrared,…
