"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.

Messenger RNA (mRNA) technology made headlines five years ago when Pfizer and Moderna vaccines arrived in the fight against COVID-19. Today, mRNA research is expanding into cancer treatments, cardiovascular regeneration, and other areas. Igor Lednev is a distinguished professor in the Department of Chemistry at the University at Albany. His lab is developing a new technique to test mRNA-based therapeutics using lasers. On this episode of “All Things Photonics,” Igor discusses his work to evaluate mRNA vaccines and treatments through Raman spectroscopy, and he explains the role laser spectroscopy will play in advancing modern medicine.

Every White House administration has its priorities. Government reform and the elimination of waste are among President Donald Trump's top priorities. Cutting down on waste is not a partisan issue; no one wants to throw away money. But how you define waste can draw a mixed response. The president has targeted scientific grants as an area in need of reform, and according to a piece published by Nature, more than 7,800 grants have been terminated or frozen. Dan Garisto is a freelance physics journalist and is one of the three authors of this piece. On this episode of All Things Photonics, he discusses the biggest findings of his work as he dug into the status of U.S. science one year into the president’s second term.

XR technology has moved from a novelty to something more ubiquitous, with real applications in communication, training, entertainment, and much more. Helping propel these systems is the newly formed AR Alliance. This group recently became a division of SPIE, and together they elevated the advances in XR systems at the AR/VR/MR Expo during Photonics West. With so many industry leaders making the trip to San Francisco for the leading event in our industry, we decided to capitalize on this rare opportunity to bring together six of the brightest minds in XR for a conversation on the future of this market, the emerging tech driving innovation, and the importance of collaboration. In this very special episode of All Things Photonics, and with the assistance of the AR Alliance and SPIE, we’re bringing to the table: Stephane Bellosguardo, VP of Global Product Marketing with Luminus Devices Brian Chen, General Manager of Appotronics Theo Marescaux, Founder and CPO of Swave Jorg Rietterer, CTO of TriLite Technologies Robert Schultz, Vice President of Optics for Vuzix And Barry Silverstein, Director of the Center for Extended Reality at the University of Rochester and former chief technology officer and senior director of optics and display products at Meta Reality Labs All of our guests have unique backgrounds and differing areas of expertise, and they’re sharing their insights on the XR market and the technology at its core on this episode of All Things Photonics.
