Staff Profile

Dr Christian Johnson-Richards

Research Associate in Photonic

Background

My interests are surrounding experimental photonics, especially telecoms range characterization of fibre devices, fibre based device manufacture, numerical modeling and software programming with Python. With an increasing interest in open-source projects including Python and the FDTD software MEEP. 



Research

I previously worked with Prof Noel Healy on my PhD titled "Perovskite Whispering Gallery Mode Resonators" here at Â鶹´«Ã½ where we developed ultra-high quality factor cylindrical micro-resonators with a perovskite single-crystal filling. I will be defending my thesis in the near future.


I previously worked with Dr Victor Pacheco Pena working with metamaterials for linear computing. Including the study of perfect splitting in rectangular waveguides and the modelling of photonic crystal waveguide junctions.


I currently work with Prof Noel Healy where we will be examining highly nonlinear perovskite based fiber based devices.
