  ABSTRACT: We demonstrate highly efficient evanescent coupling via a silica loop-nanowire, to ultra-small quantum-dot photonic-crystal cavities. It enables the tuning of both the Q-factor and the wavelength of the cavity mode independently.

  ABSTRACT: We demonstrate highly efficient evanescent coupling via a silica loop-nanowire, to ultra-small (0.5 (λ/n) 3), InAs/InP quantum dot photonic crystal cavities, specifically designed for single photon source applications. This coupling technique enables the tuning of both the Q-factor and the wavelength of the cavity mode independently, which is highly relevant for single photon source applications. First, this allows for the optimization of the extraction efficiency while maintaining a high Purcell factor. Second, the cavity mode can be matched with a spectrally misaligned quantum dot without changing the structure or degrading the Q-factor: a 3 nm resonance shift is reported. © 2007 Optical society of America OCIS code: (230.3120) Optical devices: Integrated optics devices; (230.5750) Optical devices: Resonators; (230.6080) Optical devices: Sources; (060.2310) Fiber optics and optical communications: Fiber optics; (060.1810) Fiber optics and optical communications: Couplers, switches, and multiplexers References and links

  ABSTRACT: We demonstrate highly efficient evanescent coupling via a silica loop-nanowire, to ultra-small (0.5 ($lambda$/n)3 ), InAs/InP quantum dot photonic crystal cavities, specifically designed for single photon source applications. This coupling technique enables the tuning of both the Q-factor and the wavelength of the cavity mode independently, which is highly relevant for single photon source applications. First, this allows for the optimization of the extraction efficiency while maintaining a high Purcell factor.
