Large-field cryogenic objective mirror has nearly diffraction-limited performance

Designed for use while being cooled by liquid helium, a cryogenic objective mirror with an aspherical surface has a NA of 0.93 and a field radius of 36 µm, large enough to image mammalian cells.

Shown are tuning curves for three quantum dots positioned on the waveguide at the locations shown in the inset, to achieve identical emission (a). High-resolution Fabry-Perot interferometer measurements show all three quantum dots simultaneously from an output coupler with identical emission wavelength (b).
Lasers & Sources
Quantum Sources: Squeezed quantum dots create coherent streams of quantum-ready photons

By squeezing quantum dots using unique semiconductor-based processes, coherent single photons are generated that can be used for on-chip quantum photonics that demand identical photons from multiple integrated sources.

FIGURE 1. In the scalable setting of a spatial photonic Ising machine, binary spins are encoded in the phase of a laser beam (green) by spatial modulation. Tailoring of the beam’s amplitude fixes spin-spin interaction. To find the ground-state spin configuration, the machine recurrently evolves according to a feedback signal from the camera plane. By design, maximizing the intensity in a target region (blue square) corresponds to a spin state with minimum energy.
Software
Photonics Modeling: Optical Ising machines solve complex engineering, science, and even business problems

Researchers have built the largest photonic Ising machine to date—an optical processor for solving difficult optimization problems by modeling interacting spins via a spatially varying light field.

To create a gold grating on a nanowire array (a), the nanowires themselves (vertical projections) were used as shadow masks by depositing the gold at an angle to the surface, resulting in undeposited areas (dark regions). Future nanowire-based separate absorption and multiplication avalanche photodiodes (SAM-APDs) will have faceted nanowires to help relieve lattice-mismatch strain (b).
Detectors & Imaging
Short- and mid-wavelength infrared nanowire photodiodes are uncooled

Nanowires of InAs and InAsSb on an indium phosphide substrate form room-temperature SWIR or MWIR photodiodes suitable for focal-plane arrays.
