    A space telescope architect’s odyssey from Hubble to Webb and beyond with Lee Feinberg - Ep 15

    From Hubble’s breathtaking images to the deep infrared view of the James Webb Space Telescope, space-based observatories have transformed how we see the universe. They reveal black holes, probe dark energy, trace the birth of stars, and even let us study the atmospheres of distant planets, pushing astronomy into entirely new territory. In this episode of Rays and Waves, Daniel and Steven sit down with Lee Feinberg, a true veteran of space telescope engineering. Lee joined NASA during the Hubble era and played a key role in diagnosing and correcting its original optical flaw, helping restore one of the most important scientific instruments ever built. Lee then went on to spend more than two decades on the James Webb Space Telescope as Optical Telescope Element Manager. We explore the critical decisions that shaped Webb, from selecting beryllium for its segmented primary mirror to developing new ways to test a deployable telescope at cryogenic temperatures, as well as the "cup up" optical test configuration that made full system testing possible on the ground. This conversation dives into the optical engineering behind humanity’s most ambitious telescopes and what it takes to build instruments capable of looking back to the earliest moments of the universe.

    Project Silica and the future of data storage with James Clegg - Ep 14 - Rays and Waves

    In a quiet laboratory, bursts of ultrafast laser light are etching humanity’s information deep inside glass, layer by layer, voxel by voxel. Long after today’s hard drives and magnetic tapes have failed, this glass may still faithfully preserve our data, readable thousands of years into the future. In this episode of Rays and Waves, Daniel and Steven dive into Microsoft Research’s Project Silica with their Senior Optical Engineer James Clegg. This is an ambitious effort to redefine cold data storage using focused femtosecond lasers. By writing information as sub‑micron, laser‑induced modifications to optical properties in hundreds of stacked layers, Project Silica turns glass into a truly three‑dimensional memory medium. These tiny structures are projected to remain stable for over 10,000 years and can be read out at any time using wide‑field microscopy combined with powerful machine‑learning algorithms. Our conversation explores the physics behind laser‑matter interactions, the optical engineering challenges of writing and reading data in three dimensions, and what it takes to scale such a radical storage technology. We also discuss why long‑term archival storage matters, how this approach compares to traditional media, and what it means to build technology with millennia‑long time horizons. Project Silica has been under development at Microsoft for nearly a decade, and the team recently published a comprehensive open‑access Nature paper detailing this remarkable achievement: https://www.nature.com/articles/s41586-025-10042-w If you enjoy the show, share it with your colleagues, subscribe, and leave us a review!

    LIGO and the birth of gravitational-wave astronomy with Gabriele Vajente - Ep 13 - Rays and Waves

    1.3 billion years ago, two black holes collided in a distant galaxy, sending ripples through the fabric of spacetime. On September 14, 2015, those ripples finally reached Earth and humanity detected gravitational waves for the very first time. In this episode of Rays and Waves, Daniel and Steven sit down with Dr. Gabriele Vajente, Deputy Head of Systems Science and Engineering at LIGO, who was a postdoc on the project during that historic detection. For more than fifteen years, Gabriele has been at the center of the groundbreaking technologies and discoveries that have opened an entirely new window on the universe. We explore how LIGO’s exquisitely sensitive instruments can measure distortions thousands of times smaller than a proton, the optical engineering innovations that make it possible, and what gravitational-wave astronomy reveals about some of the most violent events in the cosmos. At the heart of it all are the people like Gabriele who’ve dedicated decades to pushing physics and engineering to their limits.

    Optical tweezers with Halina Rubinsztein-Dunlop - Ep 12 - Rays and Waves

    In this episode of Rays and Waves, Daniel and Steven take a nostalgic dive back into the world where they both began their scientific journeys: optical tweezers. These remarkable tools, using tightly focused laser beams to exert forces and torques on microscopic objects, have transformed how we manipulate cells, DNA, bacteria, and so much more. Their invention by Arthur Ashkin in 1986 ultimately earned him the 2018 Nobel Prize in Physics, and today, optical manipulation stands as a thriving field with thousands of active researchers. Our guest is one of its true pioneers. For more than four decades, Halina Rubinsztein‑Dunlop has been at the forefront of exploring how light can push, twist, and guide matter. Her work spans quantum optics, optically driven micromachines, and cutting‑edge applications in biological systems. Her impact has been recognized at the highest levels, including the SPIE Gold Medal (the society’s most prestigious honor), and she will soon serve as an SPIE Director for the 2026–2028 term. Halina is also a powerful advocate for women in science, a topic we excitedly dive into during our conversation.

    An Optomechanics Bootcamp with Nathan Wallace - Ep 11 - Rays and Waves

    When we think about optical systems, lenses and light often steal the spotlight. But behind every high-performance optical instrument lies a critical foundation: Optomechanics. From precision mounts to thermal stability, the mechanical design determines whether an optical system performs flawlessly or fails spectacularly. In this episode of Rays and Waves, Daniel and Steven sit down with Nathan Wallace, an optomechanical expert from Optikos, to explore the art and science of building the structures that hold optics together. We dive into why optomechanics is more than just “hardware,” how tolerances and alignment drive system performance, and what it takes to design for environments ranging from factory floors to outer space.

    An Unsung Hero: Optical Standards with Eric Herman - Ep 9 - Rays and Waves

    Standards may not grab headlines, but they quietly shape the world. In this episode of Rays and Waves, we shine a light on the unsung hero of modern optical engineering: optical standards. From the fiber optics enabling global connectivity, via laser grocery scanners, to the precision lenses the James Webb telescope, none of it works without agreed-upon rules and measurements. These standards ensure interoperability, safety, and reliability across millions of devices. Joining Daniel and Steve is Eric Herman, a dedicated volunteer helping to develop and maintain these critical frameworks. Together, we’ll explore how standards are created, the challenges of keeping pace with cutting-edge technology, and why this work matters more than ever.

    Erwin De Baetselier and Luceda's first-time-right automated PIC design- Ep 8 - Rays and Waves

    In this episode, we sit down with Erwin De Baetselier, the CEO of Luceda, a company at the forefront of software innovation for Photonic Integrated Circuits (PICs). As PICs continue to reshape the landscape of optical systems—from data centers to quantum labs—the tools used to design and simulate them are becoming just as critical as the hardware itself. Luceda’s software empowers engineers and researchers to model, optimize, and scale photonic designs with precision and speed. We dive into how their platform bridges the gap between photonic theory and manufacturable reality, and why design automation is key to unlocking the full potential of integrated photonics. Whether you're deep in the weeds of waveguide layouts or just curious about the future of chip-scale optics, this conversation offers a behind-the-scenes look at the software driving the PIC revolution. Join Steven and Daniel as they explore the intersection of photonics and design automation with Luceda’s visionary leader.
