Nonlinear Optical Microscopy of Semiconductor Metal-Nanocavities
Riya Varghese, Shambhavee Annurakshita, Yaraslau Tamashevich +13
We use second and third harmonic generation microscopy to investigate the nonlinear optical response of GaAs nanocavities embedded in a gold film and compare them to bare GaAs nano…
Ultrafast modulation of guided-mode resonance in a nonlinear silicon nitride grating
Subhajit Bej, Nikolai Tkachenko, Robert Fickler +1
Nonlinear optical interactions in nanostructures are subjects of both fundamental research and practical applications. The optical Kerr effect, a third-order nonlinear optical phen…
High-order aberrations of vortex constellations
Rafael Barros, Subhajit Bej, Markus Hiekkamäki +2
When reflected from an interface, a laser beam generally drifts and tilts away from the path predicted by ray optics, an intriguing consequence of its finite transverse extent. Suc…
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…
