| Popis: |
In this paper, we demonstrate that a few-period circular Bragg reflector around an infinite nanowire can increase the $\beta$ factor of the fundamental mode up to 0.999 due to further suppression of the emission into radiation modes caused by a photonic band gap effect. We then apply this strategy in the practically relevant case of the finite-sized SPS based on tapered nanowires and demonstrate that the collection efficiency can be further increased. Additionally, we also show the beneficial effects of adding optimized high-index rings around the micropillar SPS. |
