MOS rib waveguide polarizers

The transmission properties of single‐heterostructure GaAs‐AlxGa1−xAs rib waveguides (RWG) clad with thin anodized oxides (0–200 A) covered by gold (MOS structures) are investigated both theoretically and experimentally. Efficient polarizers having extinction ratios of 35 dB and insertion losses <1 dB can be achieved with short (250 μm) polarizing sections. Details of attenuation characteristics depend on the dielectric constants and can be used to investigate the dielectric interface properties of MOS structure.
