Superconducting nanowire single-photon detectors with 98% system detection efficiency at 1550 nm
Optica · 2020-10-28 · 381 citations
articleOpen accessSuperconducting nanowire single-photon detectors (SNSPDs) are an enabling technology for myriad quantum-optics experiments that require high-efficiency detection, large count rates, and precise timing resolution. The system detection efficiencies (SDEs) for fiber-coupled SNSPDs have fallen short of theoretical predictions of near unity by at least 7%, with the discrepancy being attributed to scattering, material absorption, and other SNSPD dynamics. We optimize the design and fabrication of an a…
APL Photonics · 2021-05-01 · 135 citations
articleOpen accessWe developed superconducting nanowire single-photon detectors based on tungsten silicide, which show saturated internal detection efficiency up to a wavelength of 10 μm. These detectors are promising for applications in the mid-infrared requiring sub-nanosecond timing, ultra-high gain stability, low dark counts, and high efficiency, such as chemical sensing, LIDAR, dark matter searches, and exoplanet spectroscopy.
Heterogeneous tantala photonic integrated circuits for sub-micron wavelength applications
Optica · 2025-04-01 · 4 citations
articleOpen accessSenior authorAtomic and trapped-ion systems are the backbone of an emerging generation of quantum-based positioning, navigation, and timing (PNT) technologies. The miniaturization of such quantum systems offers tremendous technological advantages, especially the reduction of system size, weight, and power consumption. Yet this has been limited by the absence of compact, standalone photonic integrated circuits (PICs) at the wavelengths suitable for these instruments. Mobilizing such photonic systems requires…
A compact open microcavity platform for solid-state quantum electrodynamics

article2026-01-10
articleOpen accessNonlinear photonic platforms underpin applications ranging from spectroscopy to quantum communication, yet often face trade-offs between efficiency, loss, and scalability. An emerging platform, thin-film InGaP-on insulator, combines high χ² nonlinearity with wafer-scale fabrication. Here, we demonstrate second-harmonic generation pumped at 1550 nm with a normalized efficiency of 50±1 /W in a single-pass III–V waveguide and up to 50 mW of generated signal power. Conversely, devices enable high-br…
