2 Jun 2022 | Abstract: | Single solid-state quantum emitters offer considerable potential for the
implementation of sources of indistinguishable single-photons, which are
central to many photonic quantum information systems. Nanophotonic geometry
optimization with multiple performance metrics is imperative to convert a bare
quantum emitter into a single-photon source that approaches the necessary
levels of purity, indistinguishability, and brightness for quantum photonics.
We present an inverse design methodology that simultaneously targets two
important figures-of-merit for high-performance quantum light sources: the
Purcell radiative rate enhancement and the coupling efficiency into a desired
light collection channel. We explicitly address geometry-dependent power
emission, a critical but often overlooked aspect of gradient-based optimization
of quantum emitter single-photon sources. We illustrate the efficacy of our
method through the design of a single-photon source based on a quantum emitter
in a GaAs nanophotonic structure that provides a Purcell factor $F_p=21$ with a
94% waveguide coupling efficiency, while respecting a geometric constraint to
minimize emitter decoherence by etched sidewalls. Our results indicate that
multi-objective inverse design can yield competitive performance with more
favorable trade-offs than conventional approaches based on pre-established
waveguide or cavity geometries. | Source: | arXiv, 2206.01043 | Services: | Forum | Review | PDF | Favorites |
