Dr Lewis Carpenter

Research Staff

Lewis is a Knowledge Transfer Partnership (KTP) associate working with Covesion Ltd. and the Optoelectronics Research Centre (ORC). He received a first class Bachelors in Electrical Engineering from the University of Southampton (2009) and won the National Grid award for the highest awarded dissertation mark. Lewis continued his studies at Southampton within the ORC, under the supervision of Prof. Smith and Dr. Gates and was awarded his Ph.D in 2013.

His PhD focused on precision dicing (sawing) and micromilling techniques for silica photonic device fabrication and particularly for the production of micro optomechanical sensors and ultra-smooth micron scale features for integrated optics. Working as a Research Fellow (2014) Lewis researched the integration of precision micromilled structures with photonic waveguides for the application to optofluidic evanescent field sensing.

Currently as a KTP associate he develops ridge waveguides in PPLN (Periodically Poled Lithium Niobate) for high efficient wavelength conversion, with special interested in the application of these technologies to atom/ion trapping and single photon sources. Lewis is an avid mountain biker, runner and walker and will often be found muddy and upside down in the New Forest.
