• Miniaturising Optics with Photonic Integrated Circuits - Ep 7 - Rays and Waves

  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.

• Gerard Milburn's Path to Photonic Quantum Computing and Beyond - Ep 6 - Rays and Waves

  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!If you like the show, tell your friends and colleagues about it!

• Optical Quantum Computers - Ep 5 - Rays and Waves

  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.If you like the show, tell your friends and colleagues about it! And like, subscribe, and all that!

• Mark Nicholson's Optical Design Journey - Ep 3 - Rays and Waves

  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.If you like the show, tell your friends about it! And like, subscribe, and all that!
