Dispersion-engineered $χ^{(2)}$ nanophotonics: a flexible tool for nonclassical light

no code implementations3 Mar 2021 Marc Jankowski, Jatadhari Mishra, M. M. Fejer

This article reviews recent progress in quasi-phasematched $\chi^{(2)}$ nonlinear nanophotonics, with a particular focus on dispersion-engineered nonlinear interactions.

Supercontinuum Generation by Saturated Second-Order Nonlinear Interactions

no code implementations25 Feb 2021 Marc Jankowski, Carsten Langrock, Boris Desiatov, Marko Loncar, M. M. Fejer

We propose a new approach to supercontinuum generation and carrier-envelope-offset detection based on saturated second-order nonlinear interactions in dispersion-engineered nanowaveguides.

Ultra-low-power second-order nonlinear optics on a chip

no code implementations10 Feb 2021 Timothy P. McKenna, Hubert S. Stokowski, Vahid Ansari, Jatadhari Mishra, Marc Jankowski, Christopher J. Sarabalis, Jason F. Herrmann, Carsten Langrock, Martin M. Fejer, Amir H. Safavi-Naeini

We observe highly-enhanced effective third-order nonlinearities caused by cascaded second-order processes resulting in parametric oscillation.
