Overview

I have been Sêr Cymru II Rising Star fellow in the School of Physics and Astronomy at Cardiff University since November 2017. My expertise is in the theory and simulations of photonic topological insulators, photonic crystals, semiconductor chaotic lasers, light-matter interaction in plasmonic systems and graphene chiral metamaterials. In Cardiff, I have been working on both theory and experiments on semiconductor lasers based on photonic topological insulator.

Currently, I am leading a research group (4 PhD students) on topological photonics with a focus on the theoretical study on topological phases in photonics.

For the details of my research and news from my group, please visit the Topological Photonics Resaerch group web page.

Research

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.

  • Sêr Cymu Rising Star fellowship, "Photonic Topological Insulator Semiconductor Laser and One-Way Photonics"  (The Welsh goverment and the ERDF, £983K, approx. 5 years from December 2017 to March 2023)

Currently I am leading a team of  and 3 PhD students (Ghada Alharbi, Joe Mahoney, Shaikhah Almousa). Potential candidates for PhD studentships (EPSRC, other governement funded or self-funded etc.) and fellowships (Leverhulme fellowship, etc.) will be welcome to contact me.

Biography

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, he visited University of St. Andrews (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 Sêr Cymru Rising Star Fellow.

Professional memberships

  • Member, The Korean Physical Society (2007-2010, 2022-)
  • Member, METAMORPHOSE (2014-2015, 2022-)
  • Member, OPTICA (2022-)

Supervisions

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

Currently I am supervising 3 research students as a main supervisor (see below) and 1 research students (Annie Matthew) as a co-supervisor. Former visiting PhD students: Jochen Bissinger from Technical University of Munich and Jan Olthaus from Münster University.
