Photon counting LIDAR at 2.3 µm wavelength with superconducting nanowires
Optics express, 2019•opg.optica.org
In this work, we show a proof-of-principle benchtop single-photon light detection and
ranging (LIDAR) depth imager at 2.3 µm, utilizing superconducting nanowire single-photon
detectors (SNSPDs). We fabricate and fiber-couple SNSPDs to exhibit enhanced photon
counting performance in the mid-infrared. We present characterization results using an
optical parametric oscillator source and deploy these detectors in a scanning LIDAR setup at
2.3 µm wavelength. This demonstrates the viability of these detectors for future free-space …

We present characterization results using an optical parametric oscillator source and deploy these detectors in a scanning LIDAR setup at 2.3µm wavelength. This demonstrates the viability of these detectors for future free-space photon counting applications in the mid-infrared where atmospheric absorption and background solar flux are low.
