An optical fibre-fed superconducting electro-optic modulator with gigahertz bandwidth and attojoule per bit electric power consumption offers a fast, efficient means to connect superconducting circuits to the room temperature environment.

Wide-field mid-infrared photothermal imaging is developed to supress the resolution degradation caused by photo-thermal heat diffusion. By employing a single-objective synthetic-aperture imaging with synchronized subnanosecond mid-infrared and visible light sources, spatial resolution of 120 nm is obtained.

Optical recurrent neural networks present a unique challenge for photonic machine learning. Here, the authors experimentally show the first optoacoustic recurrent operator based on stimulated Brillouin scattering which may unlock a new class of optical neural networks with recurrent functionality.

The researchers introduce an all-silicon optical PUF that enhances IoT device security through CMOS-compatible fabrication, showcasing five unique optical responses per pixel for advanced authentication and high information entropy.

Achieving dynamic multimodal luminescence in a single material is promising but challenging. Here, the authors engineer a phosphor with dynamic multicolor luminescence and photo-thermomechanically responsive emissions by adding Mn²⁺ to a self-activated CaGa₄O₇ host.

An optical fibre-fed superconducting electro-optic modulator with gigahertz bandwidth and attojoule per bit electric power consumption offers a fast, efficient means to connect superconducting circuits to the room temperature environment.

At the University of Oklahoma, we developed a high-performance mid-infrared photonic sensing solution for the deployment of a scalable, continuous monitoring network for methane emissions in the Anadarko Basin, one of the largest oil and gas production basins in the USA.

Adaptive optics allows scientists to correct for distortions of an image caused by the scattering of light. Anita Chandran illuminates the nature of the technique.
