Quasi-static Optical Parametric Amplification
Marc Jankowski, Nayara Jornod, Carsten Langrock +4
High-gain optical parametric amplification is an important nonlinear process used both as a source of coherent infrared light and as a source of nonclassical light. In this work, w…
Ultrabroadband Nonlinear Optics in Nanophotonic Periodically Poled Lithium Niobate Waveguides
Marc Jankowski, Carsten Langrock, Boris Desiatov +6
Quasi-phasematched interactions in waveguides with quadratic nonlinearities enable highly efficient nonlinear frequency conversion. In this article, we demonstrate the first genera…
Ultrahigh-efficiency second-harmonic generation in nanophotonic PPLN waveguides
Cheng Wang, Carsten Langrock, Alireza Marandi +5
Periodically poled lithium niobate (PPLN) waveguide is a powerful platform for efficient wavelength conversion. Conventional PPLN converters however typically require long device l…
Temporal Simultons in Optical Parametric Oscillators
Marc Jankowski, Alireza Marandi, C. R. Phillips +4
We identify and demonstrate a regime of operation in optical parametric oscillators (OPOs) in which the formation of temporal simultons produces stable half-harmonic pulses. Simult…
Reduced models and design principles for half-harmonic generation in synchronously-pumped optical parametric oscillators
Ryan Hamerly, Alireza Marandi, Marc Jankowski +3
We develop reduced models that describe half-harmonic generation in a synchronously-pumped optical parametric oscillator above threshold, where nonlinearity, dispersion, and group-…
Cascaded half-harmonic generation of femtosecond frequency combs in mid-IR
Alireza Marandi, Kirk A. Ingold, Marc Jankowski +1
For the growing demand of frequency combs in mid-infrared (mid-IR), known as the "molecular fingerprint" region of the spectrum [1], down conversion of near-IR frequency combs thro…
