3D Printed Photon Shield Assembly for Low‐Noise Visual Stimulation During Two‐Photon Imaging in Mice

Advanced Materials Technologies, EarlyView.
We present the Photon Shield, an open‐hardware system for low‐noise two‐photon calcium imaging during visual stimulation in mice. Combining a 3D‐printed headplate and rail‐mounted shield substantially reduces stray‐light contamination, as quantitatively verified. Functional validation confirms reliable cortical responses. Open design files enable broad

High-Performance Semiconductor Quantum-Dot Single-Photon Sources

Nature Nanotechnology, 2017
Single photons are a fundamental element of most quantum optical technologies. The ideal single-photon source is an on-demand, deterministic, single-photon source delivering light pulses in a well-defined polarization and spatiotemporal mode, and ...

Monolithic Source of Photon Pairs

Physical Review Letters, 2012
The creation of monolithically integratable sources of single and entangled photons is a top research priority with formidable challenges: The production, manipulation, and measurement of the photons should all occur in the same material platform, thereby fostering stability and scalability.

Photon Sources for Instrument Calibration

Health Physics, 1974
Abstract A description is given of the K fluorescent X-rays, heavily filtered X-ray beams, and isotope gamma rays used at the Los Alamos X-Ray Facility to measure the energy response of radiation detectors over an energy range of 10–1000 keV. Methods of determining beam alignment, size and uniformity are discussed.

Isotropic single-photon sources

Optics Letters, 2018
Classical antenna theory establishes that there are no coherent isotropic radiators. Thermal radiators can be isotropic, but they lack temporal coherence. Here, we demonstrate that quantum interference processes enable the design of isotropic and unpolarized single-photon sources that preserve temporal coherence properties.
