Near-unity radiative quantum efficiency of excitons in carbon nanotubes
H. Machiya, D. Yamashita, A. Ishii +1
The efficiencies of photonic devices are primarily governed by radiative quantum efficiency, which is a property given by the light emitting material. Quantitative characterization…
Waveguide coupled cavity-enhanced light emission from individual carbon nanotubes
D. Yamashita, H. Machiya, K. Otsuka +2
We demonstrate an individual single-walled carbon nanotube light emitter integrated onto a microcavity and a waveguide operating in the telecom wavelength regime. Light emission fr…
High efficiency dark-to-bright exciton conversion in carbon nanotubes
A. Ishii, H. Machiya, Y. K. Kato
We report that dark excitons can have a large contribution to the emission intensity in carbon nanotubes due to an efficient exciton conversion from a dark state to a bright state.…
Enhanced single photon emission from carbon nanotube dopant states coupled to silicon microcavities
A. Ishii, X. He, N. F. Hartmann +4
Single-walled carbon nanotubes are a promising material as quantum light sources at room temperature and as nanoscale light sources for integrated photonic circuits on silicon. Her…
