Welcome to Dr Yongsop Hwang's homepage!

I am a physicist performing research in lasers, plasmonics, metamaterials, and nanophotonics. Here are some of my research projects.

Topic 1. Glass chip lasers

Glass chip lasers can host various rare earth dopants and have flexibility in design. Lasers in fluoride glass are particularly interested for their opportunities of high efficiency at infrared wavelength.
