On-chip nanomechanical filtering of quantum-dot single-photon sources
Xiaoyan Zhou, Ravitej Uppu, Zhe Liu +6
Semiconductor quantum dots in photonic integrated circuits enable scaling quantum-information processing to many single photons and quantum-optical gates. On-chip spectral filters…
Experimental probe of a complete 3D photonic band gap
Manashee Adhikary, Ravitej Uppu, Cornelis A. M. Harteveld +2
The identification of a complete three-dimensional (3D) photonic band gap in real crystals always employs theoretical or numerical models that invoke idealized crystal structures.…
Suspended Spot-Size Converters for Scalable Single-Photon Devices
Aslı D. Uğurlu, Henri Thyrrestrup, Ravitej Uppu +6
We report on the realization of a highly efficient optical spot-size converter for the end-face coupling of single photons from GaAs-based nanophotonic waveguides with embedded qua…
Universal Validity Ranges of Diffusion Theory for Light and Other Electromagnetic Waves
Maryna L. Meretska, Ravitej Uppu, Ad Lagendijk +1
The well-known diffusion theory describes propagation of light and electromagnetic waves in complex media. While diffusion theory is known to fail both for predominant forward scat…
Efficient demultiplexed single-photon source with a quantum dot coupled to a nanophotonic waveguide
Thomas Hummel, Claudéric Ouellet-Plamondon, Ela Ugur +5
Planar nanostructures allow near-ideal extraction of emission from a quantum emitter embedded within, thereby realizing deterministic single-photon sources. Such a source can be tr…
