Joint spectral characterization of SPDC photon pairs near 2 m in (Al)GaAs-on-insulator waveguides
Alexandre Z. Leger, Emil Z. Ulsig, Samuel E. Fontaine +8
Integrated photon-pair sources are a core component of chip-based quantum computing, communication, and metrology. Although such sources have been demonstrated at conventional tele…

In-Situ Measurement of Beam Divergence in a High Efficiency SNSPD Platform
Daniel W. Sorensen, Martin J. Stevens, Lynden K. Shalm +1
We implement a time-of-flight imaging technique utilizing a differential-readout SNSPD to spatially resolve detection events in a fiber-coupled detector platform. We measure the sp…
