An international team of scientists from three continents led by Dr. Petr Cígler of IOCB Prague has developed a method for creating light-emitting quantum centers in nanodiamonds in only a matter of minutes. In just one week, the process can yield as much material as conventional methods would produce in more than forty years. Moreover, the resulting nanodiamonds show improved optical and quantum properties. The breakthrough brings us one step closer to the industrial production of higher-quality and more affordable quantum nanodiamonds, which have broad applications in research and technology. The article is published in Advanced Functional Materials.

How wasted infrared light could boost solar panels, night vision and 3D printing

Researchers at UNSW Sydney have developed a nanoscale device that converts low-energy infrared and red light into higher-energy visible light, a breakthrough that could eventually improve solar panels, sensing technologies, and advanced manufacturing systems. Published in Nature Photonics, the research addresses a longstanding problem in photonics: how to stop energy from being lost before it can be used. That mechanism allowed the device to achieve photon conversion efficiencies of 8.2%, among the strongest reported for this type of architecture. "This work demonstrates a big step forward," says study lead author UNSW researcher Dr. Thilini Ishwara.

Photonics is a cutting-edge field of science and engineering focused on the generation, manipulation, and detection of light (photons). From powering high-speed internet connections to enabling precision medical diagnostics, photonics drives innovation across industries. With advancements in photonics simulation, engineers and researchers can now design and optimize complex photonic systems with unparalleled accuracy, paving the way for transformative technologies.

What Is Photonics?

Photonics involves the study and application of photons, the fundamental particles of light. It encompasses the behavior of light across various wavelengths, including visible, infrared, and ultraviolet spectrums. Unlike electronics, which manipulates electrons, photonics harnesses light to transmit, process, and store information.

The applications of photonics span diverse fields, such as telecommunications, healthcare, manufacturing, and even entertainment. Technologies like lasers, optical fibers, and sensors all rely on principles of photonics to function effectively.

Why Is Photonics Important?

Photonics is integral to the modern world for several reasons:

Speed and Efficiency Light travels faster than electrons, making photonics-based systems ideal for high-speed data transmission. Fiber-optic networks, for instance, enable lightning-fast internet and communication.

Miniaturization Photonics enables the development of compact and efficient systems, such as integrated photonic circuits, which are smaller and more energy-efficient than traditional electronic circuits.

Precision Applications From laser surgery in healthcare to high-resolution imaging in astronomy, photonics offers unparalleled precision in diverse applications.

The Role of Photonics Simulation

As photonic systems become more complex, designing and optimizing them manually is increasingly challenging. This is where photonics simulation comes into play.

Photonics simulation involves using advanced computational tools to model the behavior of light in photonic systems. It allows engineers to predict system performance, identify potential issues, and fine-tune designs without the need for costly and time-consuming physical prototypes.

Key Applications of Photonics Simulation

Telecommunications Photonics simulation is crucial for designing optical fibers, waveguides, and integrated photonic circuits that power high-speed data networks. Simulations help optimize signal strength, reduce loss, and enhance overall system efficiency.

Healthcare In the medical field, photonics simulation aids in the development of imaging systems, laser-based surgical tools, and diagnostic devices. For instance, simulation tools are used to design systems for optical coherence tomography (OCT), a non-invasive imaging technique for detailed internal body scans. Medical device consulting provides expert guidance on the design, development, and regulatory compliance of innovative medical technologies.

Semiconductors and Electronics Photonics simulation supports the creation of photonic integrated circuits (PICs) that combine optical and electronic components. These circuits are essential for applications in computing, sensing, and communication.

Aerospace and Defense Photonics simulation enables the design of systems like lidar (Light Detection and Ranging), which is used for navigation and mapping. Simulations ensure these systems are accurate, reliable, and robust for real-world applications. Aerospace consulting offers specialized expertise in designing, analyzing, and optimizing aerospace systems for performance, safety, and innovation.

Energy and Sustainability Photonics plays a vital role in renewable energy technologies, such as solar cells. Simulation tools help optimize light capture and energy conversion efficiency, making renewable energy more viable and cost-effective. Clean energy consulting provides expert guidance on implementing sustainable energy solutions, optimizing efficiency, and reducing environmental impact.
