| Abstract: | Optical waveguide polarizer is an important component in coherent optical com- munication system.In this paper,we investigate the attenuation cha(?)acteristics of single- mode metal-clad indiffusion waveguides with a dielectric buffer,and present a new method for the increase of extinction between TM_0 and TE_0 modes.The analysis would find application in the design of high-differential-attenuation metal-clad polari- zers,and in other devices using metal overlays. |
