High third-order Kerr optical nonlinearity in BiOBr 2D films measured by the Z-scan method
Linnan Jia, Dandan Cui, Jiayang Wu +8
We investigate the nonlinear optical properties of BiOBr nanoflakes, a novel two-dimensional (2D) layered material from the Bismuth oxyhalide family. We measure the nonlinear absor…

Integrated polarizers based on graphene oxide in waveguides and ring resonators
Jiayang Wu, Yunyi Yang, Yang Qu +7
Integrated waveguide polarizers and polarization-selective micro-ring resonators (MRRs) incorporated with graphene oxide (GO) films are experimentally demonstrated. CMOS-compatible…
