We demonstrate waveguide polarizers and polarization-selective MRRs incorporated with layered GO films We achieve precise control of the placement thickness and length of the GO films using layer-by-l

In this study, we present the development of waveguide polarizers and polarization-selective microring resonators (MRRs) utilizing layered graphene oxide (GO) films. Our approach involves the precise control of the placement, thickness, and length of GO films using a layer-by-layer coating method, followed by photolithography and lift-off processes. Our results demonstrate a high polarization dependent loss (PDL) of approximately 53.8 dB for the patterned GO-coated waveguide, and an extinction ratio of approximately 8.3 dB between the transverse electric (TE) and transverse magnetic (TM) resonances for the GO-coated integrated MRR. We observe that the PDL is predominantly influenced by the material loss anisotropy of the GO film for thin films, and by the polarization dependent mode overlap for thicker films. Our integrated GO hybrid waveguide polarizers and polarization-selective MRRs provide a novel and effective approach to implementing high-performance polarization selective devices for large-scale photonic integrated circuits (PICs)
