Next-Generation Fabrication for Low-Loss Quantum Photonic Devices

Next-generation quantum photonic devices routinely operate in the single-photon regime. As a result, these devices require novel device fabrication approaches to reduce losses as much as possible. Atomic layer deposition, atomic layer etch, and ion beam deposition offer potential to produce low-loss, high-performance photonic quantum devices. Such devices include single-photon emitters, superconducting nanowire single-photon detectors (SNSPDs), color-center-based devices such as diamond nitrogen-vacancy (NV) magnetometers, and more. Renzas reviews the need for and basic function of quantum photonic devices and explains how next-generation fabrication techniques can bridge the gap between today’s research-oriented first generation and tomorrow’s robust, reliable, and high-yield quantum photonic devices.
