- Abstract: Solution processible colloidal quantum dots hold great promise for realizing
single-photon sources embedded into scalable quantum technology platforms.
However, the high-yield integration of large numbers of individually
addressable colloidal quantum dots in a photonic circuit has remained an
outstanding challenge. Here, we report on integrating individual colloidal
core-shell quantum dots (CQDs) into a nanophotonic network that allows for
excitation and efficient collection of single-photons via separate waveguide
channels. An iterative electron beam lithography process provides a viable
method to position single emitters at predefined positions in a photonic
integrated circuit with yield that approaches unity. Our work moves beyond the
bulk optic paradigm of confocal microscopy and paves the way for supplying
chip-scale quantum networks with single photons from large numbers of
simultaneously controllable quantum emitters.
