- Abstract: Solid-state quantum emitters coupled to integrated photonic nanostructures
are quintessential for exploring fundamental phenomena in cavity quantum
electrodynamics and widely employed in photonic quantum technologies such as
non-classical light sources, quantum repeaters, and quantum transducers, etc.
One of the most exciting promises from integrated quantum photonics is the
potential of scalability that enables massive productions of miniaturized
devices on a single chip. In reality, the yield of efficient and reproducible
light-matter couplings is greatly hindered by the spectral and spatial
mismatches between the single solid-state quantum emitters and confined or
propagating optical modes supported by the photonic nanostructures, preventing
the high-throughput realization of large-scale integrated quantum photonic
circuits for more advanced quantum information processing tasks. In this work,
we introduce the concept of hyperspectral imaging in quantum optics, for the
first time, to address such a long-standing issue. By exploiting the extended
mode with a unique dispersion in a 1D planar cavity, the spectral and spatial
information of each individual quantum dot in an ensemble can be accurately and
reliably extracted from a single wide-field photoluminescence image with
super-resolutions. With the extracted quantum dot positions and emission
wavelengths, surface-emitting quantum light sources and in-plane photonic
circuits can be deterministically fabricated with a high-throughput by etching
the 1D confined planar cavity into 3D confined micropillars and 2D confined
waveguides. Further extension of this technique by employing an open planar
cavity could be exploited for pursuing a variety of compact quantum photonic
devices with expanded functionalities for large-scale integration. Our work is
expected to change the landscape of integrated quantum photonic technology.
