Lightwave communications is a necessity for the information age. Optical links provide
enormous bandwidth, and the optical fiber is the only medium that can meet the modern …

Even though most of the Earth's area is sheltered by the hydrosphere, the underwater world
is nonetheless a challenging puzzle that has drawn the attention of scientists and …

Free-space optical (FSO) communication technologies constitute a solution to cope with the
bandwidth demand of future satellite-ground networks. They may overcome the RF …

With the ever-increasing demand for data and the radio frequency spectrum becoming
congested, free space optics (FSO) may find a niche for situations where fiber is too …

We present a 1024-element near-infrared imaging array of superconducting nanowire single
photon detectors (SNSPDs) using a 32× 32 row-column multiplexing architecture. The array …

Single-photon light detection and ranging (lidar) offers single-photon sensitivity and
picosecond timing resolution, which is desirable for high-precision three-dimensional (3D) …

Superconducting nanowire single-photon detector (SNSPD) with near-unity system
efficiency is a key enabling, but still elusive, technology for numerous quantum fundamental …

Single‐photon detectors and nanoscale superconducting devices are two major candidates
for realizing quantum technologies. Superconducting‐nanowire single‐photon detectors …

The measurement of quantum signals that travel through long distances is fundamentally
and technologically interesting. We present quantum-limited coherent measurements of …

The dark-count rate (DCR) is a key parameter of single-photon detectors. By introducing a
bulk optical band-pass filter mounted on a fiber-to-fiber optical bench cooled at 3 K and …
