National Institute of Standards and Technology integrated quantum photonic circuits
(a) Conceptual <t>quantum</t> <t>photonic</t> circuit composed of a waveguide interferometric network with a directly <t>integrated</t> GaAs nanophotonic device containing a single InAs quantum dot. The zoomed-in image of the GaAs device region (inside the dashed boundary box) shows details of the geometry and operation principle. The light-matter interaction section of the device promotes efficient coupling between the InAs quantum dot and a confined optical mode (here, a wave confined in a GaAs waveguide). Adiabatic mode transformers allow light from the QD in the light-matter interaction region to be efficiently transferred to a Si3N4 waveguide. (b) Fabrication process in the wafer-bonding approach. The bonded GaAs / Si3N4 wafer is shown inside the dotted line, schematically at the top, and imaged in a cross-sectional scanning electron micrograph. After wafer bonding, two subsequent electron-beam lithography and etch steps (first the GaAs layer, then the Si3N4) are used to define the geometry in (a). (c) GaAs microring resonator coupled to a GaAs bus waveguide terminated into mode transformers fabricated through the process in (b). (d) Photoluminescence spectrum for the microring in (c), showing single quantum dot transition coupled to a whispering-gallery mode. Inset: second-order correlation showing antibunching characteristic of single-photon emission. Reproduced with permission.[226] Copyright 2017, Springer Nature.
