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.

The current narrative is that Artificial Intelligence is reshaping industries at breakneck speed. Is optics no exception? In this special episode of Rays and Waves Daniel and Steven host the show's very first panel discussion! They bring together six experts from across the optics landscape to try to understand: How will AI change optical engineering?

From accelerating lens design to enabling smarter photonic systems, AI promises breakthroughs but also raises big questions about trust, transparency, and the role of human expertise.

The panel consists of Craig Olsen, Jenny Atwood, Erin Elliot, Akil Bhagat, Cory Boone, and Roinan Siew, and they cover the opportunities and challenges that come with integrating AI into optical workflows.

Stuff mentioned in the episode:

• Material Craig mentioned Ronian sent out: Future of optical system and lens design in the AI era

• The effect Craig mentions is Gell-Mann amnesia effect (https://en.wikipedia.org/wiki/Gell-Mann_amnesia_effect)

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.

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.

In this episode, we explore the rise of Photonic Integrated Circuits (PICs), which aim to compress the sprawling optical setups found on lab benches into compact, chip-scale systems. These integrated platforms are becoming foundational for technologies like high-speed data communication, LIDAR, optical quantum computing, AR/VR, and biotech diagnostics—where size, modularity, and manufacturability are critical.

We take a closer look at how PICs are built, what makes them so transformative, and why the market is growing at a rapid pace. Whether you're an engineer, researcher, or just fascinated by the future of photonics, this episode offers a view into the architecture driving next-gen optical systems. Join Steven and Daniel as they explore PICs!

In the last episode of Rays and Waves about linear optical quantum computers we discussed how using photons as qubits is good in many ways. However, the biggest hurdle is that photons don’t like interacting with each other, which makes the critical two-qubit gates difficult to create.

But a 2001 discovery showed it was in fact possible to effectively make two-qubit interactions and therefore a full quantum computer solely with linear optical elements, single photon sources and detectors. This discovery catalysed a wealth of research into optical quantum computers which in aggregate has today made it a viable contender to a path to scalable fault tolerant quantum computers.

The scheme that opened the floodgates for optical quantum computers is referred to as the KLM protocol after its originators Knill, Laflamme, and Milburn.

For this episode we have the honour of talking to said Milburn on the Rays and Waves podcast!

In this episode of Rays and Waves we speak about Linear Optical Quantum Computers.

There has been lots of talk about quantum computers in the science media lately. Both companies and academic labs are hard at work to build the sought-after fault-tolerant quantum computer.

As it turns out, one approach to building quantum computers is with optics. Join us as we explore the pros and cons with this light-based approach to quantum computers.
