Advancing the Future of Augmented-Reality & Smart-Glasses Hardware with a Focus on microLED-based Display Systems 2024–Present | Meta Reality Labs (RL) I contribute to enhancing the reliability and performance of RGB microLED (µLED) panels for micro-display applications. My primary responsibilities include defining µLEDs acceptance criteria for various product lines utilizing µLED displays, as well as developing methodologies for measuring and analyzing key performance indicators (KPIs). Additionally, I am actively engaged in engineering efforts aimed at improving the overall reliability of µLED display panels. 2019–2024 | Meta Reality Labs (RL) I played a key role in developing next-generation technologies to enhance the efficiency of InGaN and AlInGaP RGB µLEDs for augmented-reality & smart-glasses displays. My work primarily focused on improving light extraction efficiency and minimizing non-radiative losses. Furthermore, I was involved in the transition of these technologies from research to manufacturing. 2016–2018 | Meta Reality Labs Research (FRL-R) I contributed to the development of microLED prototypes for proof-of-concept AR displays. My main focus was leading the GaN-µLED chip architecture design and helping to define the research roadmap. Example of product I was directly involved with: https://www.linkedin.com/posts/meta_engineering-innovation-activity-7311416145054420992-pEme?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAAh1kYBeg4gzDA03eEbmVM_RkjXQhcAe3o
I helped to design and manufacture InGaN-based and AlInGaP based micro-LEDs for the next generation of RGB high-definition displays. I was also actively involved in the characterization and analysis of the LED performance, as well as in their assembling for display applications. InfiniLED was acquired by Facebook (now Meta) in 2016.
