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.

In this episode of Rays and Waves we speak to Mark Nicholson. Few people have made a bigger impact on how modern optics is designed and analysed. Mark was for 30 years involved with Zemax, one of the optical design software giants on the market. Nowadays Mark is retired, but continues to heavily impact the optics industry by running a YouTube channel called Design Optics Fast which teaches a modern approach to optical design. Join Daniel and Steve as they quiz Mark on his career and best advice to coming optics generation.
