We propose and numerically investigate a CMOS-compatible hybrid plasmonic ridge waveguide (HPW)-based TM-pass polarizer that combines a silicon core with an Al-doped ZnO (AZO) slab separated by a silica spacer. The hybrid structure enables strong modal coupling and selective attenuation, allowing the TM mode to propagate efficiently while the TE mode is progressively suppressed through mode hybrid...
