Hyperuniform disordered waveguides and devices for near infrared silicon photonics

Posted by in categories: chemistry, internet, physics, robotics/AI, space

In a new report published on Scientific Reports, Milan M. Milošević and an international research team at the Zepler Institute for Photonics and Nanoelectronics, Etaphase Incorporated and the Departments of Chemistry, Physics and Astronomy, in the U.S. and the U.K. Introduced a hyperuniform-disordered platform to realize near-infrared (NIR) photonic devices to create, detect and manipulate light. They built the device on a silicon-on-insulator (SOI) platform to demonstrate the functionality of the structures in a flexible, silicon-integrated circuit unconstrained by crystalline symmetries. The scientists reported results for passive device elements, including waveguides and resonators seamlessly integrated with conventional silicon-on-insulator strip waveguides and vertical couplers. The hyperuniform-disordered platform improved compactness and enhanced energy efficiency as well as temperature stability, compared to silicon photonic devices fabricated on rib and strip waveguides.

Academic and commercial efforts worldwide in the field of silicon photonics have led to engineer optical data communications at the Terabit-scale at increasingly lower costs to meet the rapidly growing demand in data centers. Explosive growth in cloud computing and entertainment-on-demand pose increasingly challenging costs and energy requirements for , processing and storage. Optical interconnects can replace traditional copper-based solutions to offer steadily increasing potential to minimize latency and , while maximizing the bandwidth and reliability of the devices. Silicon photonics also leverage large-scale, complementary metal-oxide semiconductor (CMOS) manufacturing processes to produce high-performance optical transceivers with high yield at low-cost. The properties allow applications of optical transceivers (fiber optical technology to send and receive data) to be increasingly compelling across shorter distances.

More than three decades ago, physicist Richard Soref identified silicon as a promising material for photonic integration. Leading to the present-day steady development and rapid production of increasingly complex photonic integrated circuits (PICs). Researchers can integrate large numbers of massively-parallel compact energy-efficient optical components on a single chip for cloud computing applications from deep learning to artificial intelligence and the internet of things. Compared to the limited scope of commercial silicon photonic systems, photonic crystal (PhC) architectures promise smaller device sizes, although they are withheld by layout constraints imposed by waveguide requirements along the photonic crystal’s axis. Until recently, photonic band gap (PBG) structures that efficiently guide light were limited to photonic crystal platforms. Now, newer classes of PBG structures include photonic quasicrystals, hyperuniform disordered solids (HUDs) and local self-uniform structures.

Lucy Mission Overview: Journey to Explore the Trojan Asteroids

Posted by in categories: materials, satellites

Launching in late 2021, Lucy will be the first space mission to explore the Trojan asteroids. These are a population of small bodies that are left over from the formation of the solar system. They lead or follow Jupiter in their orbit around the Sun, and they may tell us about the origins of organic materials on Earth.

Lucy will fly by and carry out remote sensing on six different Trojan asteroids and will study surface geology, surface color and composition, asteroid interiors/bulk properties, and will look at the satellites and rings of the Trojans.

Underdog Pharma Could Reverse Cardiovascular Disease Which is the Leading Medical Problem

Posted by in categories: biotech/medical, life extension

Underdog Pharma is developing disease-modifying treatments for atherosclerosis and other age-related diseases.

They want to prevent or reverse atherosclerosis by removing a harmful lipid known as 7-ketocholesterol (7KC) from the arterial walls.

This CRISPR tool costs $10,000. Researchers made a version that costs 23 cents

Posted by in categories: 3D printing, biotech/medical

In microbiology, an electroporator is a tool that allows scientists to apply electricity to a cell to temporarily breach its cell wall so you can introduce chemicals, drugs or DNA to the cell. These tools are extremely useful in the lab, but they’re also very expensive. They cost anywhere from roughly $3,000 to $10,000.

Researchers at Georgia Tech just revealed they’ve found a way to create an electroporator that costs next to nothing to make. Their research was just published in the journal PLOS Biology.

These researchers were able to create a version of the electroporator that can generate short bursts of more than 2,000 volts of electricity, which they named the “ElectroPen,” using a crystal from a common lighter, copper-plated wire, heat-shrinking wire insulator and aluminum tape. They then created a case for these components using a 3D printer. They claim you can assemble it within 15 minutes once you have all the pieces.

IBM’s Plan to Design Solid-State Batteries Using Quantum Tech

Posted by in categories: computing, quantum physics, solar power, sustainability

Batteries are the key to decarboni z ing both transport and the grid, but today’s technology is still a long way from living up to this promise. IBM seems to have decided its computing chops are the key to solving the problem.

Lithium-ion batteries are still the gold standard technology in this field, and they’ve come a long way; 10 years ago they could just about get your iPod through the day, today they can power high-performance cars over hundreds of miles.

But if we want to reach a point w h ere batteries can outperform gasoline or store huge amounts of solar energy, we need some breakthroughs. So IBM has teamed up with Mercedes-Benz and its parent company Daimler to develop new batteries that could match up to our needs.

Researchers at the University of South Florida have discovered a novel feedback pathway from the brain to the eye that modulates eye pressure – a significant advancement in the effort to diagnose and treat glaucoma. Glaucoma is associated with increased pressure in the eye due to a reduce ability of the eye to maintain proper fluid drainage. The heightened pressure applies mechanical strain to the optic nerve as the nerve exits the eye, resulting in vision loss and potential blindness.

Shadow of doubt cast over China’s sovereign digital currency plan

Posted by in category: finance

Some have called for caution with regards to China’s digital currency, with the urgency to rush through Beijing’s own plan now lessened as Libra, which is perceived by Beijing as a major threat to China’s financial sovereignty, faces major regulatory obstacles worldwide.


The People’s Bank of China (PBOC) stepped up its plan to launch a sovereign digital currency in response to Facebook’s Libra digital currency.
