A deterministic approach for integrating an emitter in a nanocavity with subwavelength light confinement
Valdemar Bille-Lauridsen, Rasmus Ellebæk Christiansen, Yi Yu +1
We introduce a novel light-matter interface that integrates a nanoscale buried heterostructure emitter into a dielectric bowtie cavity, co-localising the optical hotspot and the el…

Fabrication and characterization of shape- and topology-optimized optical cavities with deep sub-wavelength confinement for interfacing with colloidal quantum dots
Mohammad Abutoama, Rasmus Ellebæk Christiansen, Adrian Holm Dubré +3
We employ a combined shape- and topology-optimization strategy to design manufacturable two-dimensional photonic crystal-based optical nanocavities that confine light to length sca…

Enhancement and speed-up of carrier dynamics in a dielectric nanocavity with deep sub-wavelength confinement
Gaoneng Dong, Ali Nawaz Babar, Rasmus Ellebæk Christiansen +4
The emergence of dielectric bowtie cavities enable optical confinement with ultrahigh quality factor and ultra-small optical mode volumes with perspectives for enhanced light-matte…
