The Dielectric Bowtie Effect: Classical Electromagnetic Edge Singularities in Subwavelength Cavities
Valdemar Bille-Lauridsen, Jesper Mørk
Dielectric bowtie nanocavities can concentrate light into subwavelength regions without the ohmic losses of plasmonic metals. We show that this enhancement is the finite-geometry r…

Lasing from a Quantum-Dot-Like Buried Heterostructure in an InP Nanobeam Cavity
Valdemar Bille-Lauridsen, Rasmus Jarbøl, Meng Xiong +4
We report lasing from a lithographically defined buried heterostructure with an estimated lateral footprint of (107 nm)^2, embedded in an InP photonic-crystal nanobeam cavity. This…

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…
