High-Q guided-mode resonance of a crossed grating with near-flat dispersion
Reuben Amedalor, Petri Karvinen, Henri Pesonen +3
Guided-mode resonances in diffraction gratings are manifested as peaks (dips) in reflection (transmission) spectra. Smaller resonance line widths (higher Q-factors) ensure stronger…

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…
