WebI am a Royal Academy of Engineering Research Fellow in the Optical Networks Group (ONG) at UCL. I recently completed my PhD in Optical Communications, in which I achieved sub-nanosecond clock and data recovery in optical switches by using clock phase caching (a technique that I co-invented at Microsoft Research in 2016) with central clock … Webof matching the expected performance of improved optical clocks in less than one hour of measurement time.
