We show that aperiodic photonic devices in silicon nitride and gallium arsenide allow high quality light confinement at visible wavelengths (Q factors up to 2200) and cavity quantum electrodynamic experiments with InAs quantum dots, respectively.

We demonstrate Anderson localization of visible light in silicon nitride photonic crystal waveguides. We measure photoluminescence resonances due to disorder-induced light localization showing quality factors of -10 000 that exceed engineered 2D phot

We demonstrate optical sensing with Anderson-localized visible light on scalablesilicon nitride photonic crystal waveguides. For a refractive index change of ≈0.38, we measure 15.2 nm wavelength shifts of an optical resonance 0.15 nm broad.

Metallic Nano-Rings for Efficient, Broadband Light Extraction from Solid-State Single-Photon Sources
Publikováno v:
Conference on Lasers and Electro-Optics.
Metallic nano-rings deposited on the sample surface, centered around single InAs/GaAs quantum dots, enhance the brightness of the emission up to ×20, further enhanced by ×10 by epoxy solid-immersion lenses, in a scalable broadband device.
