High performance visible photonic platform for manipulation of large-scale quantum emitter arrays
Abstract
The ability to manipulate large-scale quantum emitter arrays for reconfigurable entanglement states in a compact form factor remain a significant hurdle for practical implementations of quantum information systems. Visible photonic platforms, ideal for addressing atom, ion, photonic, and solid-state quantum emitters, currently have prohibitively high waveguide losses and are difficult to reconfigure due to material and fabrication challenges at short wavelengths (300-800 nm). Although there have been a few demonstrations of visible photonic systems in silicon nitride, aluminum nitride, and lithium niobate, no platform has all the necessary ingredients for a high performance visible photonic platform including- 1) low waveguide losses across the entire 300-800 nm wavelength range, 2) high-speed modulation capabilities, 3) low autofluorescence for bi-directional addressing of quantum emitters, and 4) CMOS foundry compatibility for wide dissemination. Here we propose to develop a high performance visible photonic platform based on aluminum nitride (AlN) and silicon nitride (SiN) to leverage the low losses of silicon nitride waveguides and high-speed modulation properties of aluminum nitride. Using dynamic mode coupling, we will demonstrate a highly multiplexed switching network based on higher degrees-of-freedom of light (e.g. wavelength and spatial modes) to manipulate large-scale quantum emitter arrays for large-scale entanglement. Objective 1 is to investigate and overcome fabrication-induced scattering losses in crystalline and deposited aluminum nitride waveguides across the ultraviolet-visible range. Objective 2 is to demonstrate a hybrid AlN-SiN modulator for high-speed (10-100 GHz), low-drive voltage modulation through resonant and plasmonic-enhancement. Finally, Objective 3 is to use high-speed modulation for dynamic mode coupling of frequency modes in ring resonators and the supermodes of waveguide arrays for entanglement of quantum emitter arrays.
