The


industry’s most innovative people


in association with


Photonics100: Q&A


This month, we focus on two of our 2023 honorees: TriLite Technologies CTO Jörg Reitterer and Callum Littlejohns, Cornerstone Coordinator at the University of Southampton

ominations for the Photonics100 2024 are now open (go to electrooptics.com/nominate), but that doesn’t mean we have


stopped celebrating last year’s honorees. Jörg Reitterer


EO: What is the next big thing in your area of photonics research? JR: One of the next big things in photonics is going to be the emergence of mass- market consumer augmented reality (AR) and mixed reality (MR) products. These devices will be as lightweight as the eyewear of today, while being capable of overlaying digital content over the environment, enabling a plethora of new applications, ranging from communication and entertainment to work and education. This disruptive technology has the potential to replace other products, which are ubiquitous today, such as smartphones, smartwatches, headphones, and any other display systems like TVs and monitors.


EO: What will be the biggest challenges in your area over the next year? JR: The biggest challenge for consumer AR is to develop next-generation optical architectures that satisfy the requirements of all-day wearable and daylight-bright devices in terms of size, weight, image quality, and power consumption. While AR deployment in enterprise applications is accepted, to a large degree, by trading off some of these requirements, this trade-off is not accepted in the consumer market. We at TriLite are overcoming these challenges by developing the world’s smallest, lightest, and brightest projection displays for high- volume consumer AR applications.


EO: What is the biggest personal challenge you have overcome? JR: Bringing an idea from a whiteboard discussion to filing patents, building
