dc.description.abstract	Metal clad wave guides have an extremely large differential attenuation of TE and TM states of polarization and can be used to design efficient intergrated polarizers. Described here is a AlGaAs rib wave guide polarizer in which extinction ratio in excess of 20dB been measured. The effective index method is used to design single mode rib wave guides, and losses due to gold coatings are estimated by a first order perturbation calculation. The imaginary matal index is treated as correction to the real metal index	en
