I am a Ser Cymru II Rising Star Fellow in the School of Physics and Astronomy. I have been working in the field of photonic crystals, metamaterials, plasmonics, semiconductor lasers and topological photonics. I am interested in theory and numerical modelling of topological physics and chiral light-matter interactions. My current projects focus on photonic topological insulator lasers using the III-V semiconductor nanowires, group theoretical approach to dielectric photonic topological insulators and topological pasmonics.

Sang Soon Oh received a PhD degree in Physics from Korea Advanced Institute of Science and Technology (KAIST) in South Korea (2007). During his PhD course, he visited University of St. Andrews in Scotland (2004-2005). After a post-doctoral fellowship at Electronics Telecommunications Research Institute (ETRI) in South Korea (2007-2010), he joined the Department of Physics at University of Surrey, UK as a postdoc (2010) and moved to the Condensed Matter Theory (CMTH) Group in the Department of Physics and Optical Semiconductor Device (OSD) Group in Electrical and Electronics Engineering Department at Imperial College London. In 2017, he joined the Institute for Compound Semiconductors at Cardiff University as a Rising Star Fellow.

My research background is theoretical electromangetism in composite materials such as analytical and numerical modelling of chiral metamaterials, active metamaterials and graphene metamaterials. Current interest includes photonics topological insulators and chaotic semiconductor lasers. With the Rising Star felloswship funded by the Welsh goverement, I am focusing on delveloping a photonic topological insulator laser using III-V semiconductor nanowires.  

  • Ser Cymu Rising Star fellowship, "Photonic Topological Insulator Semiconductor Laser and One-Way Photonics"  (The Welsh goverment and the ERDF, £980K, approx. 5 years from December 2017 to October 2022) 

Currently I am leading a team of 1 Postdoc (Dr Yongkang Gong) and 2 PhD students (Stephan Wong, Zeeshan Ahmad) in the Ser Cymru group. Potential candidates for PhD studentships (EPSRC, other governement funding or self-funding etc.) and fellowships (Marie-Curie fellowship, Leverhulme fellowship, etc.) will be welcome. Please contact me by email. 

I am interested in supervising PhD students in the areas of 

  • Topological physics (photonics, plasmonics)
  • Theoretical electromagnetism (analytical and numerical modelling)
  • Nonlinear and dynamic effects in semiconductor lasers (chaos, nonuniform gain effect)
  • Modelling optical property of 2D materials

An EPSRC funded PhD studentship is available in Ser Cymru group for UK or EU students. Please forward this to anyone who might be interested. https://www.cardiff.ac.uk/study/postgraduate/research/programmes/project/random-laser-with-iii-v-semiconductor-nanowires)

Title: Random laser with III-V semiconductor nanowires (Application deadline: 1 April 2019)

If you are interested in a PhD study on random laser  with semiconductor nanowires, please contact me by email.
