Photonic Doping of Epsilon-Near-Zero Bragg Microcavities
Ali Panahpour, Jussi Kelavuori, Mikko Huttunen
Epsilon-near-zero (ENZ) photonics provides a powerful route to extreme dispersion engineering, strong field confinement, and unconventional wave phenomena. A closely related concep…
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…
Purcell Effect in Epsilon-Near-Zero Microcavities
Ali Panahpour, Jussi Kelavuori, Mikko Huttunen
Epsilon-near-zero (ENZ) photonics presents a powerful platform for integrated photonic systems, enabling a range of novel and extraordinary functionalities. However, the practical…
Dispersion-induced -factor enhancement in waveguide-coupled surface lattice resonances
Jussi Kelavuori, Ali Panahpour, Mikko J. Huttunen
Diffractively coupled nanoparticle arrays are promising candidates for helping to flatten many photonic devices such as lasers, lenses, and metrology instruments. Their performance…
