A few years ago, chip shortages elevated semiconductors from an industry focus to a mainstream issue. Those shortages also exposed the dominance China held over the industry. The U.S. has since taken measures to shore up the domestic production of those precious commodities, but has it done enough? Shankaran Janardhanan, the Senior Vice President of Photonics and Radio Frequency Business at GlobalFoundries, joined the All Things Photonics podcast to discuss how companies like GF are expanding production at home, and to explain where America currently sits in the global semiconductor supply chain.

Single-photon avalanche diode (SPAD) image sensors have thrived in scientific studies. Now, they’re moving beyond the lab and into the real world for more practical applications. CMOS sensors remain the dominant technology in imaging, finding use in cell phones, automotive cameras, and medical imaging. But recent advances in SPAD could both replace and improve the use of CMOS sensors. Sebastian Bauer is the CEO and co-founder of Ubicept, a provider of SPAD sensor solutions. We caught up with Sebastian during the VISION conference in Stuttgart to discuss the rise of SPAD sensors, and the technological advances behind their growing popularity.

All Things Photonics is teaming up with the Journal Optica to bring you insights on the latest studies leading to breakthroughs in optics and photonics. What do nanophotonics and 18th-century French silks have in common? It’s all in the design. Moiré concepts are creating new opportunities in nanophotonics. In a study published in the Journal Optica, a research team from MIT demonstrated that by using twist, lattice mismatch, and interlayer coupling, moiré photonic systems could offer powerful new ways to control light, engineer optical band structures, and design reconfigurable photonic devices. Haoning Tang, an assistant professor at the Department of Mechanical Engineering at MIT, joins us to explain how this work could help further advance work on metasurfaces, photonics crystals, and so much more.

Cyclospora, an intestinal parasite, has sickened more than 22,000 Americans. The recent outbreak has been linked to contaminated lettuce from central Mexico that was later distributed in the U.S., with some researchers saying sewage contamination is the likely cause. Machine vision could prove to be vital in tracing food issues back to their original source. In this episode of All Things Photonics, BioPhotonics Senior Editor Douglas Farmer is speaking with Robb Robles, director of machine vision product management at Zebra Technologies. Robb discusses how machine vision technologies, with AI assistance, can help prevent widespread contamination of food products in the future by tracking them from the point they are harvested to when they are selected by the consumer.

One of the most exciting technologies being commercialized in the photonics space is the metalens. Metalenses are flat, lightweight optical components that manipulate light with tiny structures on their surface. They're able to replace traditional glass lenses in a lot of applications, making imaging systems lighter and more compact. In this episode, we speak with Myrias Optics’ CEO, John Fijol. The conversation covers some of the immediate applications, some that are a little bit further off, and the timeline to scaled manufacturing.

Unmanned aircraft, like drones, have become a weapon of choice. They are effective and cheap to produce, but the systems to stop them are not. Laser- and microwave-based systems are slowly coming online, but there are still hurdles to overcome before they become a staple defense on the front lines. Ganesh Balakrishnan, or “Gunny" as he’s known, is a professor of electrical and computer engineering at the University of New Mexico. He sat down with the All Things Photonics team to discuss how molecular beam epitaxy, VCSELs, PCSELs, and other photonic tech all play a part in the wider ecosystem behind counter unmanned systems.

"All Things Photonics" is teaming up with the journal Optica to bring you insights on the latest studies leading to breakthroughs in optics and photonics.

Quantum key distribution (QKD) allows encrypted information to be distributed without being intercepted. In free-space QKD, however, fluctuations in atmospheric conditions can cause distortions and impair the retrieval of the encoded information. In a study published in the journal Optica, a research team from the University of Ottawa developed a way to alleviate the effects of atmospheric turbulence on spatial mode transmission, creating an all-optical self-correction scheme for turbulence resilience using stimulated parametric down-conversion (StimPDC)-based optical phase conjugation. Aarón Cardoso, a researcher at the University of Ottawa, joins us to explain why he turned to StimPDC to solve this quantum quandary.

Before today’s ubiquitous technologies became tangible products, they began with a research proposal. The journal Optica prides itself on publishing high-impact peer-reviewed articles covering a spectrum of fields throughout optics and photonics, and for years, Prem Kumar served as the editor-in-chief for the journal. Even before taking on that title, he was familiar with the journal, having submitted several works himself. Some made the cut; others didn’t quite meet those standards. In our Spotlight conversation, Kumar shares more about his accomplishments with Optica, his work in quantum, and his own journey in photonics.
