Two regimes of confinement in photonic nanocavities: bulk confinement versus lightning rods
Marcus Albrechtsen, Babak Vosoughi Lahijani, Søren Stobbe
We present a theoretical study of dielectric bowtie cavities and show that they are governed by two essentially different confinement regimes. The first is confinement inside the b…

Nanometer-scale photon confinement in topology-optimized dielectric cavities
Marcus Albrechtsen, Babak Vosoughi Lahijani, Rasmus Ellebæk Christiansen +8
Nanotechnology enables in principle a precise mapping from design to device but relied so far on human intuition and simple optimizations. In nanophotonics, a central question is h…
