Site-selective enhancement of Eu emission in delta-doped GaN
Amelia R. Klein, Hayley J. Austin, Fumikazu Murakami +7
Europium-doped gallium nitride (GaN:Eu) is a promising platform for classical and quantum optoelectronic applications. When grown using organometallic vapor-phase epitaxy, the domi…
Circularly polarized cavity-mode emission from quantum dots in a semiconductor three-dimensional chiral photonic crystal
Shun Takahashi, Yuzo Kinuta, Seiya Ito +5
We experimentally demonstrated a circularly polarized cavity mode in a GaAs-based chiral photonic crystal (PhC) containing a planar defect. Low-temperature photoluminescence measur…
Excitation efficiency and limitations of the luminescence of Eu3+ ions in GaN
Dolf Timmerman, Brandon Mitchell, Shuhei Ichikawa +3
The excitation efficiency and external luminescence quantum efficiency of trivalent Eu3+ ions doped into gallium nitride (GaN) was studied under optical and electrical excitation.…
Circularly polarized vacuum field in three-dimensional chiral photonic crystals probed by quantum dot emission
S. Takahashi, Y. Ota, T. Tajiri +3
The quantum nature of light-matter interactions in a circularly polarized vacuum field was probed by spontaneous emission from quantum dots in three-dimensional chiral photonic cry…
Giant optical rotation in a three-dimensional semiconductor chiral photonic crystal
S. Takahashi, A. Tandaechanurat, R. Igusa +4
Optical rotation is experimentally demonstrated in a semiconductor-based three-dimensional chiral photonic crystal (PhC) at a telecommunication wavelength. We design a rotationally…
