Various 3D sensing, imaging, illumination, and ranging uses, as well as their convergence in new lidar technology, could be made possible by implementing optical phased arrays (OPAs) in integrated photonic circuits. Although large aperture sizes are required to enable medium- to long-range lidar, current integrated OPA approaches must be scaleable regarding control complexity, power consumption, [..]

Researchers have conducted a ground-breaking operation to show “hybrid” quantum networking, which is a first for the world. The method, which combines two ways of encoding information in light particles called photons, may enable more powerful and reliable computing and communications. Quantum networking systems can encode information as discrete variables (DVs) in particles or continuous [..]

A group of researchers has advocated for the use of UV light as a ‘particularly efficient, easily deployable, and economically affordable’ means to limit the spread of coronavirus. The study, involved experts in the fields of virology, immunology, aerosols, architecture, and physics, analyses the possible methods to prevent Sars-Cov-2 propagation in indoor spaces. Small indoor [..]

Advanced nuclear magnetic resonance (NMR) spectroscopy pulse sequence editing enables noninvasive assessment of the spatial distribution of chemical composition and diffusion behavior of materials. However, the spectral resolution and analytical approach for heterogeneous materials could still be improved. Here, scientists create tools for thoroughly analyzing substances and their dynamics in whole bodies and heterogeneous systems [..]

A new thermal scanner called a “Multi-Person Thermal Scanner” can precisely measure the skin temperatures of up to six individuals at once. The scanner’s main purpose will be to assist businesses and healthcare organizations in swiftly and effectively identifying people suffering from a fever, one of the main symptoms of Covid-19. A non-intrusive, cutting-edge thermal [..]

Researchers have shown that recyclable, flexible electronics have a high potential for use in the production of cheaper solar cells, touchscreens, wearable ‘e-skins,’ and next-generation responsive windows. These materials, created using a simple, low-cost fabrication process, have the potential to replace traditional transparent conductive oxides such as indium tin oxide (ITO), which is a required [..]

Biophysicists have created a high-throughput super-resolution microscope to examine mammalian cells’ nanoscale dynamics and structures. This microscope reveals the twists and turns of an organelle crucial to cell division in unparalleled detail. Centrioles are a thousand times smaller than a human strand and about one hundred times smaller than a mammalian cell. Since the techniques [..]

Engineers have created a novel 3D printing method that enables the printing of flexible materials with precise tuning. The group successfully printed materials using a droplet-based, multiphase microfluidic system with possible uses in soft robotics, tissue engineering, and wearable technology. Until the product is finished, printing material is repeatedly added to the structure using conventional [..]

The tree of life is full of species that transitioned from aquatic to terrestrial. Some species occasionally went oppositely. A CT scan showed new information about the inner ear anatomy of ancient reptiles called thalattosuchians, providing details about one of these evolutionary turning points. Following a protracted semiaquatic phase, these now-extinct crocodile relatives entered the [..]

Whether it be computing systems, sensors, or lidars, the modern photonics business is constantly working to make its products smaller.
