Publikováno v: Micromachines, Vol 13, Iss 8, p 1194 (2022)

We experimentally investigate power-sensitive photo-thermal tuning (PTT) of two-dimensional (2D) graphene oxide (GO) films coated on integrated optical waveguides. We measure the light power thresholds for reversible and permanent GO reduction in sil
