Multi-slot optical Yagi-Uda antenna for efficient unidirectional radiation to free space
Jineun Kim, Young-Geun Roh, Sangmo Cheon +10
Plasmonic nanoantennas are key elements in nanophotonics capable of directing radiation or enhancing the transition rate of a quantum emitter. Slot-type magnetic-dipole nanoantenna…
Absorption enhancement in amorphous silicon photonic crystals for thin film photovoltaic solar cells
Ounsi El Daif, Emmanuel Drouard, Yeonsang Park +8
We report on very high enhancement of thin layer's absorption through band-engineering of a photonic crystal structure. We realized amorphous silicon (aSi) photonic crystals, where…
Near-field photoluminescence study of InAs/AlGaAs quantum-dot-based nanoclusters: band filling effect
Young-Jun Yu, Han-Eol Noh, Mun-Heon Hong +5
We have performed near-field spectroscopy and microscopy of the InAs/AlGaAs quantum-dot-based nanoclusters. It is observed that the photoluminescence spectra of spatially confined…
