Photonic rocket structure grown by site-selective and bottom-up approach: A directional and Gaussian-like quantum emitter platform
Semiconductor quantum dots (QDs) integrated with photonic nanowires are one of the
representative platforms for high-purity single photonic sources. However, conventional
photonic nanowires suffer from severe scattering at the edge owing to the small footprint. For
this reason, tapered structures have been adopted to achieve directional emission with
minimized scattering, and hence, high light collection efficiency. So far, various tapered
structures have been demonstrated by using top-down etching fabrication or catalyst …
