Welcome to the Bradley Group
Developing new materials and devices for emerging micro- and nanophotonic systems
Recent NewsCongratulations to Renjie for his publication in Optical Materials on spectroscopy of Er-Yb co-doped alumina films.
Congratulations to Khadijeh for her manuscript accepted in OSA Continuum on four-wave-mixing in hybrid TeO2-Si3N4 microring resonators. Congratulations to Dawson for his paper published in Optics Express on Er-Yb co-doped optical amplifiers on silicon! Congratulations to Hamidu, Cameron and Jeremy for their recent publications in the IEEE Photonics Journal on engineered dispersion and nonlinearity in hybrid TeO2-Si3N4 waveguides, Optics Express on tellurium-oxide functionalized SWG waveguides and Thin Solid Films on low-loss germanium oxide thin films, respectively. Hamidu and Henry recently presented at the CLEO 2020 virtual conference. The team also contributed four presentations at the Photonics North virtual conference in May 2020. Welcome to the group Alex and Sam for summer research! Henry Frankis recently published his work on erbium amplifiers in Photonics Research. Khadijeh Miarabbas Kiani recently published her work on thulium on-chip amplifiers in Optics Letters. |
