Lasing from complete set of topological states in two dimensional photonic crystal structure
Changhyun Han, Minsu Kang, Heonsu Jeon
Recently, topologically engineered photonic structures have garnered significant attention as their eigenstates may offer a new insight on photon manipulation and an unconventional…
Absorbing photonic crystals for thin film photovoltaics
O. El Daif, E. Drouard, G. Gomard +9
The absorption of thin hydrogenated amorphous silicon layers can be efficiently enhanced through a controlled periodic patterning. Light is trapped through coupling with photonic B…
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…
