Abstract |
|
In this paper, the metal clad optical waveguide polarizer have been analysed and presented. The metal's that were used are Gallium Arsenide and Aluminium for the cladding purpose of comparison and analysis. It was found that the variation between TE mode and TM mode when Gallium Arsenide is used as the cladding is less as compared to Aluminium. This is due to the metal cladding itself will cause a cut-off region in the polarizer. Gallium arsenide may have fewer modes compared to aluminium and which resulted in the variation of the graphs between the two metals used. We have also shown that there is a slight drop of the TM to TE loss ratio when the buffer layer thickness is increased. It was also found that the high extinction ratio results in the high and linear attenuation in the fiber. |
