Enhancement of bulk second-harmonic generation from silicon nitride films by material composition
K. Koskinen, R. Czaplicki, A. Slablab +8
We present a comprehensive tensorial characterization of second-harmonic generation from silicon nitride films with varying composition. The samples were fabricated using plasma-en…

Electrically Tunable Optical Nonlinearities in Graphene-Covered SiN Waveguides Characterized by Four-Wave Mixing
Koen Alexander, N. A. Savostianova, S. A. Mikhailov +2
We present a degenerate four-wave mixing experiment on a silicon nitride (SiN) waveguide covered with gated graphene. We observe strong dependencies on signal-pump detuning and Fer…
